His signature for these shows was Johnny Williams.

I love that John Williams, in giving the main theme to the (French) Horns, also wrote them a (rapidly) ascending chromatic scale run as part of that theme-it's something only valved Horns can do, and something that could not have been written/heard in classical or other music before Horns got their full valve systems.

Just for the record, the Lost In Space Theme was written and conducted by John Williams... Yes, THE John Williams.

I'm right now listening to this orig. version which STILL gives me the chills WHAT an thrilling piece of musical mastery. It caught thee entire focus of our family of 6 instantly...we were t-o-t-a-l-l-y hooked from there-on-in! "That does not compute!"

Just for the record, BOTH themes were written and conducted by John Williams.... Same John Williams who wrote and conducted the most famous Sci-Fi soundtracks of all time, from Jaws and Star Wars and Close Encounters to Superman and Indiana Jones soundtracks.

I never got tired of the first theme music, made me want to get up and explore the unknown in space.

i love both versions! if you watched as a kid in the 60's you have got to watch lost in space again.i think it was johnathans the robots last time together. very cool show,the jupiters' set was redone with real LOVE!

THE FIRST THESE IS MY FAVORITE! MAN THAT BRINGS ME BACK TO WHEN I WAS 4 OR 5 I LOVED THIS SHOW! THAT HAD TO BE 1973

i also thought this would be "the other one" the iconic staccato trumpet playing the double 16th notes

Love this show and it was before my time. Nothing beats that cool theme song lol so catchy too. Love the Jupiter too which is explains why I love UFO ships and I had a cool model of the robot :D it was sweet.

Definitely the first version hands down.. Love the Brass instrumental over the bells and flutes..

Thing is l remember watching the third season premiere episode and hearing this theme song. Loved it so much more than the previous 2 seasons.

Taking them both at face value: the two versions are exquisitely subtley different rhythmically. The first syncopates the horn section with the orchestra. The second doesn't do that! It demotes several bars to 7/8, syncopating the whole orchestra. Extremely subtle to my ears!

Love the first theme, brings back memories of my cousin playing video games to it.

the seemingly divergent tempi of the flutes and bells was fully intentional for reasons known only to john Williams. but that has to be the jazziest thing he ever composed, hands down.

Both 5he classic original theme and newest version is great 👍🏾

DAM'N I recently learned the theme from Star Wars on piano and didn't realize how much great music John had written. I am a John Williams fan and THANKS for this video. Keeping REAL music alive.

#1 in my opinion is the bestest.........

This is great...i have not heard this since it was on tv in the sixties.

This sure bring back memories , where did all the time went ,

John Williams at it again! #boss

Now that I know this theme was composed by John Williams, I can't NOT hear it as "The Jurassic Park Theme on Cocaine."

I never knew john wiliams composed this no wonder its so good

Fantastic! And ahead of its time.

I thought the TWO versions would be Season 1/2 (B&W), with the staccato trumpets; and #2 with the two different renditions offered here...

Neither of those are the first version, they are just two versions of the second version

"You know who should write the music for Star Wars? The guy who did Lost in Space!" - George Lucas

I JUST LOVE THE NEW VERSION!!!

This is not "2 versions of THE lost in space theme"...this is 2 versions of "A" lost in space theme! There are 2 completely different pieces of music that are both valid claimants to the title

When I saw the title of this video, I assumed it would include the theme from Seasons 1 and 2 as well as this Season 3 (and beyond) version. Maybe the title should specify that. Both were written by (as then listed) Johnny T. Williams

He was credited then as Johnny Williams

This is so Iconic , Its like jump on board the J@2 or you will miss the trip of a life time!

I loved watching this show as a kid.

I remember the reruns in the early 70's and hearing "1997"...and figuring out I would be 33 years old...just as much as fantasy as anything on the show to me then..LOL

I used to watch this show every Saturday!!

You've taken the words out of my mouth. The French horn playing in the first version is top notch. That opening chromatic scale? Wow! Most impressive. Not many can do that. But in the second version...??? They were clearly different players.

The themes were great even back ground music in the program was brilliant too

Love lost in space

Totally Awesome bring some more

Thanks, John Williams.

This the one I always liked

I think Apollo 440 did a good job covering this circus music to that epicness.

there's another Lost in Space Theme song

brings back so many memories

I LOVE what you've done here. Either one should have been in the movie version. Hats off to RobertRobin10. Keep up the good work.

These two versions are practically the same. These are variations of the 2nd and 3rd seasons, whereas the 1st season is completely different.

Mi serie favorita saludos de José desde Lima gracias

This theme is catchy...but I still like the Season 1 theme better.

This a- la Go-Go version is an insult to those (many)among us who grew up with the epic- sounding original theme. It is ridiculously campy and kitschy

brings me back to the good old days of 1976

Maravilhosa versão ! obrigado por compartilhar.

Lol thought I was the only one who noticed!

The first is the classic theme. The second didn't sound right.

The best Lost in Space theme by far.

Always loved the Horns in F

love this version of the lost in space theme

I never heard the similarities between the theme song of Lost in Space and the Jurassic Park theme. Slow this down and the main themes do have a likeness.

Everyone's talking about the similarity between this and the Jurassic Park theme, but I'm over here saying the Asteroid Field music from Empire Strikes Back is so similar that Williams had to have intentionally composed it from a variation of the Lost in Space theme.

Dr. Smith was the first obviously gay television character that I can remember. 01.01.15

This is awesome!

Tremendous good run on the French horn. Good player.

More great scores from our John Williams!

That second version sounds out of sync with itself. Weird.

love this one :)

I always thought that this song was borrowed from the violin solo in Del Shannon's song Runaway.

hey back2backband bro i agree with because i did the same and my sister would fight me for the tv and i always won so i could watch lost in space

I think what most people think is a French horn is actually a melophonium . It gives the same sound as a French horn but is much easier to play ...The French horn is very difficult to play and limited as to what it can do .

There are two different Lost In Space themes, but this is two versions of the second theme. This doesn't include the orignal theme. The 2nd version on this video is terrible.

That second version... See, on the one hand, I was never able to master the musical instrument of my choice, so I'm no musician and am somewhat loathe to criticize where I can do no better. On the other hand, there's nothing wrong with my ears- at least there wasn't until I heard that affront to my hearing. I feel like someone just raped my ears.

It's SO John Williamsy....

Had 3 versions, lost in space

Irwin Allen may have cheaped out on the effects, but he did spend money on the music.

He did.

That second one isn't very good. It doesn't sound like it was actually in the show - maybe it's from one of those albums where they couldn't afford the rights to include the actual TV themes, so they had them recreated [often poorly].

Sounds like a school band

mi programa preferido perdidos en el espacio

Funny how they switched to more serious music in the third season, just as the show was getting more silly.

Watching/hearing it again.... God help the City of Prague Philharmonic. Prague is a city I've been to and absolutely, truly love. But my God, that's a TERRIBLE recording of the Lost in Space theme..

The first one is the theme from 3rd or fourth season on

'Travesty?' That's kind of harsh. I grew up watching this show (Dr. Smith, Jonathan Harris talked my dad into hair transplants in a limo ride - I thought being in the car with him was the COOLEST). While I don't hate the 1st theme, I always liked the 2nd theme better. It was faster. As far as the 2nd version here, it's pretty damn close to it's actual arrangement, and, as the theme has no lyrics, and was played almost verbatim, I don't get the grip about it.

ITS BACK BAYBEE

@bronxborn1974 you're right I think the ratings were going down so they needed a more uptempo livelier theme song,but remember the show went from a serious sci fi to a silly slapstick sureal show with the robot and dr smith doing endless shtick!!!!

@leuszler You are so right!

my thoughts exactly

I don't remember the music from these intros ever being played this fast? Why is it so speeded up? Great music, BTW! I never can figure out which theme song I liked better. The first one was real good, too.

John Williams wrote the orginal.

was the second version from the motion picture?

First version is, of course, a classic. Hard to improve on that. Good try with the second version, but the tempo is unfortunately quite off. Fix that, and it would be a lot better.

Both versions rock

Anyone remember the monkey thing named Debbie? It scared the shit out of me when I was a kid.

I don't know where the second version came from, but its hard to improve on John Williams, and needless to say, improving wasn't done here. Sounds like the tracks aren't even synced.

LEVEL SEPT 7 YES 💖💖💖💖💖💖💖.

Why does the second one sound as the the woodwinds are playing in a different time Than the brass. It's a little awkward. I'm turning my head just a bit to get them into alignment. LOL

The second theme in this video wasn't used on the show.

What the hell is this mash-up? The first version of the theme begins normally but then midway transitions to the rancid electronic version from "Television's Greatest Hits." The second version is a bizarre nightmare of weird competing time signatures that don't make any sense. I have no idea where that second recording came from but it is absolutely dreadful!

Land of giants had 2 versions

Oh Will! The pain! The pain! No, actually I like the first one much more. Second one sounds like tracks are out of phase.

What about the other theme song?!

The second version sound like it came from a high school band.
