Kirsty Young's castaway this week is the comic and actress Whoopi Goldberg. As a child she used to practise the acceptance speeches she was sure she would one day make - little surprise then that she's one of a handful of people to have won an Oscar, a Grammy, a Tony and Emmy awards.

Favourite track: Lovely Day by Bill Withers
Book: Letters to a Young Poet by Raine Maria Rilke
Luxury: Wise potato chips
