Jimmy Stewart as The Six-Shooter. Somehow never played this before. Well-written show, and Stewart was at least as good on radio as he was in fillums. This one's called "The Coward" (27 September 1954).
And the best radio show ever, Vic and Sade: "Robert And Slobert Are Scoundrels" (24 July 1944).
Update: Anybody's head would be turned by a firkin of homemade mucilage.
