American Epic Part 4: The Sessions

As Desert Island Discs reaches 75, today's custodian of the island, Kirsty Young, introduces the 1982 Bafta-winning Arena classic. It celebrated Roy Plomley and his magical idea on their 40th anniversary. By then, everyone who was anyone had been cast adrift and washed up on Roy's island. Arena's castaways include 40th anniversary guest Paul McCartney, Frankie Howerd, Trevor Brooking, Professor J K Galbraith, Russell Harty and the great comedian Arthur Askey.
