Mariella Frostrup is joined by former personal assistant to Nelson Mandela, Zelda la Grange; comedian John Moloney and country-blues musician Rattlesnake.

Zelda la Grange grew up in South Africa as a white Afrikaner who supported the rules of segregation. Yet just a few years after the end of apartheid she became Nelson Mandela's trusted assistant for the next 19 years. In her book, Good Morning, Mr Mandela, she tells the story of how a young woman had her life, beliefs and prejudices transformed by the President of South Africa. Good Morning, Mr Mandela is published by Allen Lane.

Rattlesnake Annie - known as Rattlesnake - is a country-blues musician. Born of Cherokee heritage on a cotton and tobacco farm in Paris, Tennessee, she began writing songs at 10 and soon afterwards formed a trio with her cousins, The Gallimore Sisters. At16 she was lured to Memphis by blues and rock n' roll where she learnt her craft under the tutelage of Muddy Waters and Lightnin' Hopkins. Her latest album is called World Of Love.
