Once the Andrews Sisters had established themselves as viable movie stars by performing the Oscar nominated/chart-topping hit "Boogie Woogie Bugle Boy" in 1941's Buck Privates, Universal signed the singing siblings to a multi-picture pact. The films, churned out at the rate of two or more per year throughout World War II, were always low budget, top-heavy with musical numbers, and often had popular band-leaders of time (like Harry James or Woody Herman) as co-stars. They were squarely aimed at teenagers, and were a reliable source of profit to the studio.
Like most movie studios at the time, Universal often used its "program pictures" to promote their up-and-coming contract players. This film is one of a number of low budget Andrews Sisters musicals which cast newcomers like Donald O'Connor, Peggy Ryan and Gloria Jean in secondary and supporting roles. Once the studio's Francis the Talking Mule franchise made O'Connor a star of sorts, he left Universal for M-G-M, where he enjoyed even greater success.
