Where Did You Get That Girl? is a 1941 comedy film. The title comes from the popular song of the same name, which dates to 1913 and was written by Bert Kalmar and Harry Puck. The song figures prominently in the movie (and has been featured in other films before and since).
The plot of the movie is about the misadventures of a swing band trying to break into the big time. Helen Parrish plays the band's vocalist.
