Ex-Queen members Brian May and Roger Taylor have agreed to play at a birthday celebration for Nelson Mandela in 2008.

The former President of South Africa will make an appearance at the concert, which marks the politicians 90th birthday, say reports from the BBC.

The concert is being organised to help raise the profile of the Mandela 46664 Aids campaign. The two rockers were involved in the creation of the charity in 2003 with fellow musicians Dave Stewart and Bono.

The concert driven campaign - which is named after Mandela's prison number from his stint in jail on Robben Island in South Africa - aims to benefit those "on the frontline to fight HIV."

Beyonce and Bono headlined the first event organised by the campaigners in South Africa in 2003. There have been further events in Spain and Norway since the charity's conception.
