Glen Gray and the Casa Loma Orchestra with vocalist Kenny Sargent recorded "Blue Moon" (Rodgers - Hart) in 1934. The melody was written for the Hollywood Revue of 1933 but unused for the film. The melody was used again the next year for the movie Manhattan Melodrama. Within months Lorenz Hart changed the lyric to the "Blue Moon" we know.
In 1961 bi-racial group The Marcels (Cornelius Harp, Fred Johnson, Gene Bricker, Ron Mundy and Richard Krauss) hit the top of the charts with this fun cover. The story of this recording is covered well in the Stu Phillips biography "Stu Who?: Forty Years of navigating the Minefields of the Music Business". Stu produced the hit version.
