Queen stars Brian May and Roger Taylor have signed up to perform at a concert in London next year to mark Nelson Mandela's 90th birthday.
Brian May and Roger Taylor helped launch the 46664 campaign
The charity concert is being held to raise awareness of Mandela's 46664 HIV Aids campaign, set up to help those "on the frontline to fight HIV".
May and Taylor helped found the 46664 campaign in 2003, alongside fellow music stars Dave Stewart and Bono.
The former President of South Africa will attend the concert on 27 June.
A worldwide music-led campaign, 46664 takes its name from the prison number Mandela was assigned during his 18-year-sentence on Robben Island in South Africa.
Bono and Beyonce Knowles headlined the first concert in South Africa in November 2003.
Spain and Norway have also played host to concerts, in addition to a second gig held in South Africa in 2005.
In January of the same year, Mandela lost his son to Aids.
