U2 are getting a new singer -- at least temporarily, while Bono recovers from a bike accident. Bruce Springsteen will step into the group's vacant frontman role for its performance in Times Square tonight for World AIDS Day.

The Irish band was scheduled to play in New York City long before Bono busted his left shoulder blade, among other body parts, after taking a nasty spill while avoiding a collision with another cyclist in New York a couple of weeks ago. Rather than cancel their appearance while their singer recovers from surgery, the other members of U2 have enlisted Springsteen and Coldplay's Chris Martin to sing their songs.

According to JamBase, Bono noted in a press release that "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 ... 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.”

The event starts at 7:30PM ET, and includes performances by other artists, too, including Carrie Underwood and Kanye West. If you can't make it to Times Square, or just don't want to fight the massive crowd, you can check out the show live as it happens here.
