Watch HDToday. Arena celebrates Roy Plomley's Desert Island Discs with the help of many celebrity castaways, including Frankie Howerd, Russell Harty, Trevor Brooking, the Lord Mayor of London, Professor JK Galbraith and Arthur Askey. The special guest for the 40th anniversary programme was Paul McCartney who was also a fan of the show: 'I love its homeliness. It conjures up the best in traditional British pleasure, like the great British breakfast. It's an honour to be asked'.
