Clay's and Kelly's voices are great in this video. Clay can harmonize with anyone...He is totally amazing... The IT Tour was amazing. I was at the Detroit concert, and the screams for Clay were incredible.... I'll never forget it...

American Idol has really jumped the shark since then. That was pure talent with no bells and whistles.They both can stand on the stage and sing, no auto tuning, backup or tooling.

I'm back I have been listening to Clay's Joyful Noise Christmas tour...What a blessing it was to see him and hear his Christmas music..He looks and sounds great as always..Just loved them all...I listened to each tour stop over and over..I can't wait to see what he has for us in 2013..

I don't care how old I get, I will always be a Claymate! it's been like 13 years and I'm still pissed that he didn't win AI!!

Loved this video and these two together. Someday I hope these two will be able to tour together again...

They sound GREAT together!

the way Clay sings is so elegant. Man! the crowd gets crazy with him! Kelly did a great job too.

I remember this like it was yesterday. Im lucky to have been there. The place went crazy when clay came out, had chills!!

My 2 fave singers ❤

This song should have been recorded by the two of them !!!! I love this duet!!!!

Wow they both sound great 2gether! the crowd went ape shit when Clay came out on stage. Kelly such a beautiful powerful voice.

What a great job they did on this song. I listen to Clay's music everyday. He has the voice of an Angel...I could listen day and night. God bless you Clay AIken~~!!

I’m thrilled that I saw them together at Nassau Coliseum on Long Island back when Kelly was only 21 years old I even have a pic taken in a group with them both! Autographed and all. Love them both still….

this is AWESOME. They harmonize so well together!!! I love it! and clay is gorgeous.

I mean.. wow.. I'm speechless.. what a greta cover to an AMAZING song. just plain beautiful.

I think they're the best out of American Idol.

They smoke that song! WOW! Just makes you realize that American Idol puts out the Greatest Singers! RE: Phillygrl5 comments above, I was in the audience and both sets of fans stayed until the end. It was a packed house tell they turned off the lights. Some people still love to try to start wars between the fan groups! Long Live CLELLY!

wow that was a great collaboration!! i wud fall asleep wit their voices

a very powerful combination... i'm in love with this version of the song, It's just super!

this gave me chills. amazing performance. :P

Love when Clay comes out and the crowd goes wild..And you can see a big smile on Kelly when they do. Love the two of them together. GREAT DUET!!

Absolutely Beautiful!! They both have a wonderful and blessed gift.

Wow, two of the best vocals ever on the show. So far I must say that Kelly and Clay had the best female and male vocals on the show respectively. Unbelievable performance by the both of them!!

I seen this live in Omaha during the Independece tour there. It was the loudest screaming I have ever heard at any concert I've ever been to! When Clay first showed up on stage it was deafening and you cpuld feel the excitement in the air. I will never forget that and this video reminded me of that eveing all over again. Clay is simply amazing!

I am a huge fan of Clay but I love Kelly too. They both have really excellent voices and I think that they are both great together! I would have loved to have attended that concert.

Love this song

one of my favorite songs of all time, plus sung by one of my favorite singers, Kelly clarkson... aww.. im so happy. haha

Truly unbeatable!

Really enjoyed the Independent Tour. Love the combination of Clay and Kelly, Kelly and Clay. What a magical tour.

These two are destined to become the two most successful idols. Period. They sounded great together. I can see them doing this on some award show 10 years from now.

Here the proof that a GREAT song lives forever....Thanks Steve, thanks Jonathan, you rule :))

simply terrific

Love it. Clay has IT in capitol letters. I love them both. Will you listen to that applause? Clay & Kelly supah stahs!! Clay also has the best voice I've ever heard.

What great voices they have.

wow, the crowd went crazy when Clay came out... i dont blame them :) they were awesome! Should've made a cover track for this song :)

awesome vocals from both great Idols..

I just love this song and the two of them singing it.. I love how the crowd goes crazy when Clay comes out.. And if you look close to Kelly you can see a big smile on her face when they do go crazy... Love love this song.

What an awesome job they did on this song.. I love Clay's music.. Clay and Kelly are great together..

Very nice. Great talents.

I ever had felt this way about this song because Kelly clarkson and clay Aiken impressed me and Dominic zeman

wow. this is just FANTASTIC!

They sound amazing togther 😍 Wish they had recorded some songs together too.

An excellent song

Two very genuine voices and two talented people.

I LOVE THEM BOTH!!!

I love Clay Aiken. Still.

I'm impressed. I didn't think I would be, but It was well done.

they sang that reallll good!!!!

OMG!!! that is amazing!!

omg i never knew they did a duet! ofcourse this the perfect song for them..they have the perfect voices for it! although kellys always been my fave..their both great :)

Aww...how sweet. I really think that Clay and Kelly should record a song or two together. They both have such great voice! I was at this concert in Chicago. I remembered how annoyed I was with all the screaming audiences. I wished they would just shut up and listened to the song. I had to contain myself and try not to scream the whole time. If I can do it, they can too.

This was my prom song...special meaning

kelly is sooo much better! love her voice. clay did alright. kelly is so adorable haha and she can SING. who couldnt like her?

top idols.........clay aiken, kelly clarkson, kerry underwood, and of course jennifer hudson. simply the best.

Great Song

they're the best contestants of AI Ever!!!of all seasons male and female

That was brilliant!

clay is a spectacular singer

this song is amazingg but i love the original one but still kelly n mariah still sing it soo damm beauiful espeicallly mariah

Two of my favorite singers in the world...where is Clay??

Welcome. Clay has a wonderful voice. He has so many fans that really love him. And have been with him for 10 years. Just wanted to say welcome. Enjoy all of Clay's music. He sure has awesome talent and will melt your heart.

That was amazing!!! They are really good together

Great video! Thank you!

The love shown to Clay here is overwhelming me, I can't even imagine how he felt when the screams were so loud for him almost deafening. WOW.. just couldn't love him any more, then he signals the audience to give Kelly the love. Now that is our BF.

OMG!!!! clay's coming out with a new CD next year?! yeah!!! i LOVED this song with the both of them!

I admit Kelly is good!! But Clay....WOW! His is so unbelieveable!! I adore him!

Best vo8ces of American

Amazing!

this was awesome

i love it thanks

they were both amazing but I'm gonna give it to my girl KC!

memacute -- If you mean lightly tapping the side of the mic with his left hand soon after he first came onstage, I noticed it as well. I believe he stepped into a dead zone for the monitor speakers and couldn't hear himself over the crowd. Patting the mic like that is a signal to the crew, "is this mic working?" If I'm right, he did an excellent job of staying on pitch without being able to hear himself. That can't be learned, you either got it or you don't. I'd say he's got it.

I didn't watch idol when either one of them were on but the are goood!

HAHAH I WAS THERE. And at that point I was pretty much three rows from the stage.

They look so cute together

WOW I am a new fan of Clay!

go clay and kelly!!!!!!!!!!!!!

Kelly is the most modest, humble and friendly celebrity i've known...she doesn't mind just wearing a pair of jean and t-shirt because dress doesn't have anything to do with your talent...even if u wears the most expensive and vogue dressses is no use if u can't sing...she can sing alright....

OMG lol the SCREAMING is insane hahaha

clay aiken nailed it!!

@aussiechic06 ITs called a tribute and a cover. Its Kellys favorite part of touring. She has plenty of her own original songs but since she likes some songs so much she likes to sing them in honor of that artist and song.

WOW!!!

wow!

These two performed that song again more recently -- I think Kelly's last tour. Clay surprised the crowd by joining Kelly on stage. I'm sure it's here on youtube -- they both sounded great just like this video.

I love this song open arms because This is a true loyal tribute To Dominic Joseph Patrick zeman Because he would be happy that you are singing his song open arms because he passed away since Thursday

WOw, this is the same version as Mariah's version, love it!!

Definitely! Sheesh!

Both are great, but it seems that most people were there for Clay. The screams when he appeared on stage must have been deafening. I wish I would have been there! (because of Clay mostly)

I admire Kelly for performing with Clay when he gets such a huge reception from the audience. I think they sound great together.

I just love to hear them both. my favorite performance was the one on St.Paul, when Clay gave her the yellow roses. i think that Clay, Kelly and Carrie have been the must successful ones on AI.

@Eragon11777 I'm taking a shot at answering your question: I think that singers rely on a muscle around the stomach area, called the diaphragm, when it comes to singing. I think it helps with singing loudly because it helps with air control, as it's right under the lungs. I'm guessing Kelly finds it easier to sing loudly and more steadily with her hand there. Of course, I just know of the existence of the diaphragm. I could be totally wrong with my explanation.

I don't know how people figure they can hear a song if they don't stop screaming. I know I couldn't hear it as I would have liked for all that noise. And this is one I really would have liked to hear. Maybe someday they can sing together in a quality environment. That would be fantastic.

If he weren't gay what a couple they would have made eh? Not an anti gay comment, I just think they are so good together. Our daughter's best friend is a gay man and she had him as her man of honor at her wedding. They are deep and fast friends for life.

he was just telling the sound guy to turn his mic up. you can see after he repeatedly taps his mic, he points up to tell him to turn it up.

i love them singing this :) hehe, kelly's so short ^
