The "Hooray for Hollywood" music at the beginning and end of the film is a promotional trailer for an RKO film made in 1937 (Hooray for Hollywood (1937)) featuring the
Benny Goodman Orchestra. The members of the orchestra are the male voices singing, and the voice saying "Be an actor, see Mr. Factor, he'll make your kisser look good" belongs to drummer
Gene Krupa. The actual promo film itself is featured in the documentary Benny Goodman: Adventures in the Kingdom of Swing (1977).
