Leona Performs for Mandela

After attending a dinner in honour of Nelson Mandela's 90th birthday on Wednesday, Leona continued to sing praises for the birthday boy at a fundraising concert in his honour at Hyde Park in London.

Proceeds from the event are in aid of Mandela's 46664 charity, which is currently campaigning to raise awareness of the severity of the disease.

46664 was Mandela's prison number while he was incarcerated for his anti-apartheid views.
