Performances from the telethon, which will be broadcast from New York, Los Angeles, London and Haiti, will also be available on iTunes for 99 cents each starting Saturday, and all proceeds will go to Haitian relief.

Haiti's Prime Minister Jean-Max Bellerive told CNN's Christiane Amanpour that at least 72,000 bodies had been recovered following of the 7.0-magnitude earthquake that struck the impoverished country on Jan. 12. A 6.1-magnitude aftershock has since rocked Haiti on Wednesday morning. The United Nations says an estimated 10 percent of the buildings in the city have been destroyed, leaving 300,000 people homeless, and many are fleeing the destruction.

Jay-Z, Bono and producer Swizz Beatz have written and recorded a song together for the cause, according to BBC News. "Bono got a call from a producer, Swizz. He and Jay-Z wanted to do something for Haiti," U2 guitarist The Edge told Irish radio station 2FM. It is not clear as to whether the song will air during the telethon.

The two-hour, commercial-free special — starting at 8/7c on ABC, CBS, NBC, Fox, CNN, BET, the CW, HBO, MTV, VH1 and CMT — will be headlined by George Clooney in Los Angeles, Wyclef Jean in New York and Anderson Cooper in Haiti.
