Johnny Borrell of Razorlight performs at the 46664 concert in honour of Nelson Mandela in Hyde Park, London June 27, 2008.[Agencies]

Sporting her trademark black beehive hair, a black and white dress and high-heeled shoes, the 24-year-old appeared nervous at first but received one of the biggest cheers of the night.

At the close of the concert she was joined on stage by Jerry Dammers, who helped organise the 1988 concert, and many of the other performers.

Accompanied by a raucous audience, they sang Dammers' Free Nelson Mandela, which became an anthem for the anti-apartheid movement in Britain in the 1980s.
