Prior to release of "Sun Valley Serenade", "At Last" was performed in the film by Glenn Miller and his orchestra, with vocals by John Payne and Lynn Bari, dubbed by Pat Friday. Studio head Darryl Zanuck reportedly said, "There are too many big ones in this. Let's save one for the next." The "At Last" vocal by Payne and Bari was thus deleted, although instrumental versions remained in the film, including in the Black Ice Ballet finale. The vocal version was included in the movie Orchestra Wives (1942), which also featured the Glenn Miller orchestra.
