Amy Winehouse, Dame Shirley Bassey, Queen and Annie Lennox are some of the top acts scheduled to appear at a concert for Nelson Mandela's 90th birthday this summer.
The former South African president will travel to London's Hyde Park for the June 27 event.
Razorlight, Jerry Dammers, the Sugarbabes, Simple Minds, Jamelia and the Soweto Gospel Choir will also play at the concert.
Proceeds will go to the 46664 campaign, which raises awareness about the impact of AIDS, especially in Africa, and promotes effective HIV prevention measures throughout the world.
46664 was Mr Mandela's old prison number.
"You all know that I am supposed to be retired but my friends and the charitable organisations that bear my name want to use my 90th birthday year to raise funds to continue our work and so of course I want to help them," Mr Mandela said.
"So, we have a bargain - I am going to London and they will host a concert in Hyde Park, which will raise awareness of our continuing work and much needed funds."
Former US President Bill Clinton, British Prime Minister Gordon Brown, actor Will Smith and American chat show host Oprah Winfrey are amongst those who will attend the 90th birthday concert.
Tickets for the three-hour event go on public sale on Friday 9 May.
