Wonder gave and electrifying performance in front of thousands of fans and several world leaders on Saturday at the Global Citizen Festival. Bono gave a funky, rousing introduction to Wonder, who headlined the second annual concert. Wonder wowed audience members, who danced and sang along to songs including "Superstition" and "Isn't She Lovely." "This is a global celebration," Wonder yelled to the crowd. We will end extreme world poverty in our lifetime. Wonder has been a United Nations Messenger of Peace with a special focus on disabilities since 2009. Messengers have recognized talents in the arts, academia and sports and help bring attention to UN work. The Global Citizen Festival coincides with the UN General Assembly. Fans earned free tickets for helping spread the word or volunteering to help end world poverty. The event was organised by Evans, 29, who put on the Make Poverty History concert in Melbourne in 2006.

We can power the world," Ban told the crowd. Will.i.am and Olivia Wilde were among the celebrity attendees. Wonder ended the five-hour event, electrifying the crowd during his hour-long performance. He even teased concertgoers before singing "Signed, Sealed, Delivered I'm Yours." "That's it!" he yelled, then added: "Y'all wanna jam some more?" Other performers included John Mayer, Kings of Leon and Alicia Keys, whose set included "No One" and "Empire State of Mind." "I believe if we don't care about each other, who will?" the singer said. Help me celebrate tonight so we never forget. Wonder also had a touching moment when he sang John Lennon's "Imagine" and encouraged the audience to lobby for more gun laws. "Can you believe blind people have guns?" he said. Let's keep it real. Ridiculous. Last year's Global Citizen Festival featured Neil Young and Crazy Horse, Foo Fighters and The Black Keys. The festival's nonprofit partners pledged $US1.3 billion ($1.4 billion) in new fundraising commitments last year. Wonder, who played the piano and harmonica, was joined onstage by R&B singers Maxwell and Janelle Monae. "I can't believe this is happening," Maxwell gushed when singing "Superstition."
