One of the longest-running programmes on British radio, with a format and theme tune that are familiar to many millions of people, Desert Island Discs is a Sunday morning institution. In the 71 years since it was first broadcast (29 January 1942), there have been only four presenters: Roy Plomley, Michael Parkinson, Sue Lawley and the current incumbent Kirsty Young.
Guests on the show are asked to choose eight pieces of music that they would take with them to a desert island. They speak a little about that music, but mostly they speak about themselves. Over the decades, the programme has featured almost 3,000 fascinating and often moving interviews with a vast array of public figures, from Ivor Novello to Alfred Hitchcock to Margaret Thatcher to Zadie Smith.
Right now, 2,000 of these programmes are available to listen to online or to download from the BBC's website. It is a wonderful archive that brings together politicians, scientists, religious leaders and cultural icons. Once you begin to explore, it is difficult to stop.
So, if you want to know why Aung San Suu Kyi chose to take a Tom Jones record to her desert island, or why Prime Minister David Cameron chose Ernie by Benny Hill, then you can visit the archive by clicking the photograph (of original presenter Roy Plomley) below. You can also read a very interesting article about the programme on the New Statesman website.
