The song "Put Me To the Test" was a complete reworking of an instrumental used in the 1937 Fred Astaire musical A Damsel in Distress (1937) The lyrics for it had already been written by Ira Gershwin, and the original melody by his brother George, but because the song had already been heard only as an instrumental in that film, George Gershwin's melody was discarded in favor of a new one by Jerome Kern when "Cover Girl" was made, and Ira Gershwin's lyrics to the song were finally heard.
