Blue Moon was written in 1933 by the iconic song-writing team Richard Rodgers and Lorenz Hart. It was first written for the 1933 film The Hollywood Revue under the title Prayer, however due to production changes the piece was excluded from the film. It was again used in the 1934 film Manhattan Melodrama under the title The Bad In Every Man. When song publisher Jack Robbins had Hart write more commercial lyrics to the piece it became Blue Moon. It became a massive hit and his most popular song.
