To thank America for all it's done in the fight against AIDS, Bank of America presented A (RED) THANK YOU: a special live performance from Times Square featuring U2, Chris Martin, Carrie Underwood, Kanye West, and Bruce Springsteen!

These five superstar music acts took over Times Square in New York City on World AIDS Day (December 1st) to support (RED) and the fight against AIDS by sharing their music during a very special show. You can re-live all the action for the next two days with iHeartRadio's iHeartRED Radio station. You can tune in on the app or online.

Kicking off the event was a few words from former President Bill Clinton. In fact, President Clinton told everybody that Bono had e-mailed him just so he could introduce the show!

The first artist to rock the stage was Coldplay frontman Chris Martin, who joined U2 to sing two of their hits "Beautiful Day" and "With Or Without You." Bono may have been home in Ireland recovering after his recent injury, but Chris did an amazing job filling in for him. He even wore a t-shirt that said "substitu2" (get it?).

A glowing Carrie Underwood took the stage next. She was wearing a thick long coat, but you could just make out her growing baby bump! Carrie beautifully sang "Change" and her new single "Something In The Water." Even pregnant, Carrie can really belt it out!

Up next was Kanye West. The rapper performed a medley of his hits including "Power," "Jesus Walks," "Black Skinhead," "Stronger," and ended his set with "Touch The Sky." Yeezus was extremely energetic and animated on stage, drawing roaring cheers from the audience (and probably everyone watching at home).

Closing out the night was The Boss, Bruce Springsteen. The rock star also joined U2 to perform "Where The Streets Have No Name" and "I Still Haven't Found What I'm Looking For." Also taking the lead in place of Bono, Bruce gave a shout-out to the Irish rocker and said, "I wanna send this one out to Bono in Ireland!" 

Organized by Bono's RED organization, the goal is to let everyone know that December 2nd is Giving Tuesday. For every dollar donated to RED, Bank of America will match it with an additional two dollars. Bono says, "This year is a World AIDS Day like no other. The world reached a tipping point in the fight against AIDS -- more people were newly added to life-saving treatment than were newly infected with the virus. A lot of people are calling it the beginning of the end of AIDS. We wouldn't be at this point without American leadership, people from the left and the right. Today, 13 million people have access to life-saving treatment, up from 300,000 just over 10 years ago. Americans don’t know the role they've played in this fight. Tonight's event is to inform them and thank them."
