All four members of U2 were originally scheduled to perform at the World AIDS Day (RED) performance Monday night in Times Square. But with lead singer Bono still recovering from serious injuries suffered from a bike accident last month, the group announced two capable substitutes: Bruce Springsteen and Coldplay‘s Chris Martin.

“Friends have stepped in to save U2’s surprise World AIDS Day (RED) performance, which was jeopardised by Bono’s November 16th bike accident in Central Park,” the band wrote on their Facebook page. “Adam Clayton, The Edge and Larry Mullen Jr. will be joined by Bruce Springsteen and Coldplay’s Chris Martin, each of whom will take a turn as frontman on the U2 songs. Appearing at the personal invitation of U2, Springsteen and Martin have graciously donated their time and talents to save the World AIDS Day event from cancellation.” The band has dubbed themselves U2 Minus 1 for the concert.

Kanye West and Carrie Underwood are also scheduled to perform at Monday’s event supporting (RED), an organization that aims to prevent HIV transmission from mother to child.

“This year is a World AIDS Day like no other,” Bono said in a statement. “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,” added the singer. “Today, 13 million people have access to life-saving treatment, up from 300,000 just over ten years ago.  Americans don’t know the role they’ve played in this fight.  Tonight’s event is to inform them and thank them.”

Fans unable to attend the show can watch a live stream on YouTube beginning at 7:30 p.m. EST.

Last month, Bono suffered what doctors called a “high energy bicycle accident” while attempting to avoid another rider in New York’s Central Park. He was rushed to a nearby hospital for multiple X-rays and CAT scans followed by five hours of surgery. The singer suffered numerous serious injuries, including a “facial fracture involving the orbit of his eye,” three separate fractures of his left shoulder blade and a fracture of his left humerus bone in his upper arm. Bono’s doctor told Rolling Stone the singer will “require intensive and progressive therapy,” but “a full recovery is expected.”
