A 46664 spokesman said Mr Mandela attended the Hyde Park gig to thank the British people for a concert at London's Wembley Stadium in 1988, which called for his release from jail.Precisely 46,664 tickets - after Mandela's prison number during his 27-year incarceration for trying to topple South Africa's apartheid regime - went on sale for the three-and-a-half-hour concert.The African liberation hero, who turns 90 on July 18, is now in frail health.
"The world remains beset by so much human suffering, poverty and deprivation," Mr Mandela said at a fundraising dinner during the week.
"It is in your hands to make of our world a better one for all, especially the poor, vulnerable and marginalised." The 46664 campaign, which has seen four previous multi-artist concerts, aims to raise awareness of the HIV/AIDS epidemic which is rife in sub-Saharan Africa.
South Africa is one of the countries worst-hit by HIV, with 5.41 million people living with the illness.
