Shout Factory! has a new Marx Bros. TV Collection DVD set that includes an episode of the Jack Benny Program dated to April 3, 1955. Great episode where Jack goes on You Bet Your Life to try to win $3000 disguised as a violin player. I just got the set today, thought I'd share for those not in the know.
