Bono and Lady Gaga are giving a fan a once-in-a-lifetime experience for a good cause

Bono joined a star-studded Jimmy Kimmel Live! for the (RED) Benefit Show to help raise money for the fight against AIDS. While there, Bono revealed that he would be teaming up with Lady Gaga to give one fan who donates to the cause at Crowdrise a very special gift: They will write a song about that person. The site says Bono and Gaga will “… find out everything about you and then write you your very own medley.” The winner will also get an autographed copy of the lyrics.

Bono took part in another kind of collaboration on the show, joining Pharrell Williams for a slowed down, soulful version of the Bee Gees “Stayin’ Alive.” By the end of the song, the words “stayin’ alive” had changed to “saving a life,” with Williams adding “(RED) is” before it.

Other celebrities were on hand to display products available at www.red.org/products/ and at amazon.com/red, with a portion of the proceeds going to the charity. Channing Tatum used his serious acting skills to hawk a TV, but Kristen Bell and Mila Kunis just wanted him to take his shirt off. That’s when he gave us this gem: “I’m not a piece of meat; I’m a piece of meat with feelings.”

Will Ferrell appeared as an audience member with some delicious issues. “I’m a bit of a chocoholic,” Ferrell said, “which means I’m addicted to chocohol, which is a real condition and it’s RUINED MY LIFE!”

Snoop, Kerry Washington, Chris Rock and Brad Paisley were also there to lend a hand.
