Sunday Night at the Radio!

Jack Benny: Jack returns from his command performance in London. Dinah Shore is the guest. Funny (of course) (19 November 1950).

Update: The Tallulah Bankhead reference explained in her wiki:

In 1950, in an effort to cut into the rating leads of The Jack Benny Program and The Edgar Bergen & Charlie McCarthy Show which had jumped from NBC radio to CBS radio the previous season, NBC spent millions over the two seasons of The Big Show starring "the glamorous, unpredictable" Tallulah Bankhead as its host, in which she acted not only as mistress of ceremonies but also performed monologues and songs.[14] Despite Meredith Willson's Orchestra and Chorus and top guest stars from Broadway, Hollywood and radio--including Fred Allen, Fanny Brice, Groucho Marx, Ethel Merman, Gracie Fields, Vera Lynn, Jimmy Durante, Martin & Lewis, George Jessel, Judy Garland, Ethel Barrymore, Gloria Swanson, José Ferrer and Judy Holliday, The Big Show, which earned rave reviews, failed to do more than dent Jack Benny's and Edgar Bergen's ratings.

Update II: Tallaluhwiki, ya'll.

And a Vic and Sade: "Rush's New School Clothes" (24 August 1942).
