During the 1970s, BBC shows like Morecambe and Wise, the Two Ronnies, the Generation Game, Dad's Army and Parkinson transformed the world of television entertainment and delighted audiences in their millions. The man behind the success of these shows was entertainment impresario Sir Bill Cotton, who died in 2008. Stars including Ronnie Corbett, Sir Michael Parkinson and Bruce Forsyth celebrate the golden age of entertainment and remember the man who made it happen.
