Berlin wrote "A Singer, A Dancer" for Crosby and his planned co-star Fred Astaire; when Astaire became unavailable, Berlin re-wrote it as "A Crooner – A Comic" for Crosby and Donald O'Connor, but when O'Connor left the project, so did the song. Another song written by Berlin for the film was "Sittin' in the Sun (Countin' My Money)" but because of delays in production Berlin decided to publish it independently. Crosby and Kaye also recorded another Berlin song ("Santa Claus") for the opening WWII Christmas Eve show scene, but it was not used in the final film. Their recording of the song survives, however, and can be found on the Bear Family Records 7-CD set titled "Come On-A My House".
