Groucho Marx
Associated-Rediffusion for ITV, 17 June to 9 September 1965 (13 episodes in 1 series)
Quiz show with Groucho Marx of Marx Brothers fame. The format was possibly the same as You Bet Your Life, which was revived by Bill Cosby (seen in the UK on Channel 4 in the 1990s).
British DJ/presenter Keith Fordyce appeared on every show as a co-host acting as a sort of translator in case Groucho got mixed up with the English-American language.
