William Gillespie sang "Blues In The Night" (Harold Arlen - Johnny Mercer) in the 1941 movie of the same name. Wikipedia: "When they finished writing the song, Mercer called a friend, singer Margaret Whiting, and asked if they could come over and play it for her. She suggested they come later because she had dinner guests—Mickey Rooney, Judy Garland, Mel Tormé, and Martha Raye. Instead, Arlen and Mercer went right over. Margaret Whiting remembered what happened then: They came in the back door, sat down at the piano and played the score of "Blues in the Night". I remember forever the reaction. Mel got up and said, "I can't believe it." Martha couldn't say a word. Mickey Rooney said, "That's the greatest thing I've ever heard." Judy Garland said, "Play it again." We had them play it seven times. Judy and I ran to the piano to see who was going to learn it first. It was a lovely night."

Woody (Woodrow) Herman and his Orchestra hit number one in 1941 with "Blues In The Night (My Mama Done Tol' Me)" with Woody on lead vocal. Co-writer Harold Arlen is the other voice. Members of his various Herds include Stan Getz, Terri Gibbs, Neal Hefti, Shelley Mann, Red Norvo, Shorty Rogers and Zoot Sims.
