Bono, Shakira, Alicia Keys and Wyclef Jean were among the stars who joined former U.S. President Bill Clinton for a roundtable discussion on youth activism in New York City on Saturday (29Sep07). Clinton hosted the event at Harlem's legendary Apollo Theatre, where he called on each young audience member to "be a citizen servant, a giver, because we have to have a vital society". He added, "You know, I grew up playing music, and all my life I've wanted to play the Apollo." After the superstar panel took questions from the crowd, Keys and Jean both took the stage to perform short sets.
