On March 24th, 1940 Jack Benny was guest-star for a dramatic role on Orson Welles' Campbell Playhouse over CBS airwaves.

The story they chose was "June Moon," a play by George S. Kaufman and Ring Lardner, based on the Lardner short story "Some Like Them Cold," about a love affair that loses steam before it ever gets started.

At the center of June Moon is Fred Stevens, a young aspiring lyricist who journeys from Schenectady to New York City, where he hopes to make a name for himself in the world of song publishing and night clubs. On the train he meets dental assistant Edna Baker, and the two embark upon a friendship that evolves into love for her and fondness for him. While struggling to become a Tin Pan Alley notable, Fred takes a shine to his composer partner Paul's glamorous, gold-digging sister-in-law Eileen. The two men sell a song to a music publisher and it develops into a hit. Ultimately, revelations about Eileen's true character help return Fred to his senses and Edna, whom he realizes he truly loves.

The cast included Orson Welles (Candy Butcher), Jack Benny (Fred Stevens), Benny Rubin (Maxie Schwartz), Gus Schilling (Paul Sears), Bea Benaderet (Lucille Sears) and Virginia Gordon (Edna Baker). Lee Patrick reprised her Broadway role as Eileen. Ernest Chappell was the announcer.

"June Moon" was Orson Welles penultimate episode with The Campbell Playhouse. He would leave the series after March 31st to focus on the production of his first feature film, Citizen Kane.
