“Moonlight Cocktail” is a 1942 big band song recorded by Glenn Miller during World War II. The music was composed by Luckey Roberts with lyrics by Kim Gannon.
The song was originally recorded by Glenn Miller and his Orchestra on December 8, 1941, the day after the attack on Pearl Harbor. The song had its first public performance in January 1942 on WABC radio in New York City. The 78 rpm disc was released by Bluebird Records as #11401. Vocals were by Ray Eberle and The Modernaires. “Happy in Love” was on the B-side. It was the best-selling record in the United States for ten weeks, from February 28, 1942 to May 2, 1942, and was the number two record for that year after Bing Crosby’s White Christmas (Wikipedia).
