A 46664 concert in London's Hyde Park on June 27 will double-up as an early 90th birthday celebration for Nelson Mandela.

The former South African President and Nobel Peace Prize winner revealed that his actual birthday -- on July 18th -- will be spent with family, but that he would attend the London event as part of his commitment to his 46664 campaign to fight HIV and AIDS.

"My friends and the charitable organizations 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," the septuagenarian statesman said in a statement issued today at a Johannesburg press conference. "London wants to celebrate my birthday and I said I would go if they would raise funds for our charities. So, we have a bargain - I am going to London and they there will host a concert in Hyde Park, which will raise awareness of our continuing work and much needed funds."

Tickets for the London event will be distributed by online pre-registration at www.46664tickets.com. The line-up of artists has not yet been disclosed.

The 46664 Hyde Park concert comes 20 years after the Wembley Stadium "Free Mandela" concert, which was staged on June 11, 1988 in celebration of the then-incarcerated leader's 70th birthday.
