Nelson Mandela: Dancing with Ladysmith Black Mambazo choir

8 December 2013 Last updated at 00:01 GMT

The South African choral group Ladysmith Black Mambazo has won international recognition and three Grammy Awards.

Perhaps best known for singing with Paul Simon on his album Graceland, the musicians are global ambassadors for South African culture.

They also had close ties with Nelson Mandela - and on a recent tour of the United States they told the BBC about that bond, and about their signature sound.
