JOHANNESBURG – Nelson Mandela waved to the crowd and Colombian singer Shakira had fans dancing in their seats as South Africa began saying farewell to the 2010 World Cup in emotional and pulsating fashion.The anti-apartheid icon had kept a low profile during the monthlong tournament, having decided against attending the opening game following the death of his great-grand daughter.Driven in a small golf cart alongside wife Graca Machel, a smiling Mandela was welcomed by a thunderous mix of vuvuzelas and roars from the crowd. He shook hands with officials before leaving the field a few minutes later.Shakira, backed by South African Afro-fusion band Freshlyground, did one last rendition of the cup’s theme tune, Waka Waka (This Time for Africa) after a lights show and fireworks.
