At the June 27 show, performers such as Leona Lewis, Annie Lennox, Dame Shirley Bassey, Queen, Simple Minds and Kirsten Dunst's ex, Johnny Borrell and his band Razorlight, will rock the stage. Other attendees include Bill Clinton and Forest Whitaker.

The concert comes three weeks before Mandela's actual birthday, and proceeds will go to his charity, 46664, which helps people affected by HIV and AIDS. 46664 was Mandela's prisoner number during his 27-year incarceration (which ended in 1990) by South Africa's apartheid regime.
