The creativeness of this choreography never ceases to amaze me, but even more impressive about this clip to me is how well they utilized and adapted to such a small stage while performing a huge number.

The fact that they had to change the staging to fit the tiny area they were performing in... they are such pros... so incredible!!!!!!!!

He is such a versatile actor and I think he needs to do more broadway!

I don't think I've ever heard a crowd cheer so much after a performance on any late night show.

Flawless accent, brilliant pitch & outstanding dance moves. He had such great charisma & enthusiasm. If anyone ever thought he would be stuck as the specky boy who lived they were wrong. He has endless talent & this is an excellent example of just how varied his performances can be.

Frank Loesser was such a genius. I'm not particularly proud to be an American EXCEPT when I see something like this. What pure joy!

This is the textbook definition of what Broadway calls The 11 o'clock Number.

I have watched a couple different versions of the performance of this song... and I really appreciate the camera shot from the back with him doing the flip. I wonder if he ever did gymnastics. That's really great body form.

Wow! The physicality of the dance moves was really impressive! And to do all that while singing! Wow!

His singing has improved pitch wise since I say the show in March. I always find it interesting how they re-stage big production numbers like this to fit in an actually very small studio such as this one. Rob Ashford deserves a lot of credit for where he has taken this show as both a director and a choreographer.

How they do not collide is beyond me. I love this show.

When this first aired on Letterman I saved it on my DVR. I was astounded! Love love love the energy and footwork and fun. Almost everynight I played it before going to bed. After a day of bad news and grief and strife it really cheers me up. Tonight I accidently deleted it. Ack! So glad I found it here. Thank you MichaelParkNet for posting this.

saw this on broadway this summer, and i'm not even kidding, it was the BEST broadway show i've ever seen. daniel was FANTASTIC, and i didn't feel like i was watching harry potter which was great. john larroquette was also AMAZING, everyone needs to see this show!!!!!!!

Have seen the show four times.....!!! Just love it, the whole thing is incredible--funny, energetic, well-acted. Didn't know Dan before this but his incredible courage, work ethic, energy, determination and flat out talent have floored me. Plus he's beautiful and everybody in the show loves him. He goes out and sign autographs every night although he's exhausted. And he made a pact with John Laroquette to NEVER miss one show, which is practically unheard of on Broadway. BRAVO Dan!!

Seeing Daniel hit all those notes and dance moves flawlessly -- incredible!

whoa. i'm really impressed. dan has great stage presence.

Saw it live on Broadway with my wife and son and his wife. Loved it!!! I knew the story but my son was so impressed with Radcliffe. Of course he only knew him as Potter. We were all impressed. Terrific revival. Excellent

He is definitely one of the coolest, most talented people of all time!
