Discarded and Revived

"A Kiss to Build a Dream On" is a song composed by Bert Kalmar, Harry Ruby and Oscar Hammerstein II. 

In 1935, Kalmar and Ruby wrote a song called "Moonlight on the Meadow" for the Marx Brothers film A Night at the Opera but the song was not used. Hammerstein later adapted the lyrics to be "A Kiss to Build a Dream On" and it was recorded by Louis Armstrong in 1951. 

It was also performed by Armstrong as well as by Mickey Rooney with William Demarest, by Sally Forrest, and by Kay Brown in the 1951 film "The Strip," and was a recurring theme in the film.
