WHAT IS DESERT ISLAND DISCS? HERE'S YOUR ANSWER COURTESY OF WIKIPEDIA:
Desert Island Discs is a long-running BBC Radio 4 programme. It was first broadcast on 29 January 1942 and is said by the Guinness Book of Records to be the longest-running music programme in the history of radio.  Guests are invited to imagine themselves castaways on a desert island, and to choose eight pieces of music to take with them; discussion of their choices permits a review of their life. They must also specify which one of these pieces they regard most highly. Aside from music, they are permitted one book, excluding the Bible or other religious work and the complete works of Shakespeare, which are already present on the island to force more original choices. They also choose one luxury which must be inanimate and of no survival value, though large supplies of champagne seem to be allowed. The names and selections of some of the more recent guests are listed separately.
