Let's Make Music is a 1941 American musical film directed by Leslie Goodwins starring Bob Crosby, Jean Rogers and Elisabeth Risdon. It was produced by RKO Pictures and written by Nathanael West. The film's songs include the classic "Big Noise from Winnetka".

Newton High music teacher Malvina Adams (Risdon) is asked to retire since attendance in her classes keeps dropping each year. Trying to prove she's still got it, Adams composes a school fight song which finds its way into the hands of bandleader Bob Crosby (playing himself) who turns it into an overnight hit. Though her niece Abby (Rogers) protests, Malvina travels to New York to perform her song with Bob's band, while her niece falls for the bandleader. The newness of the song fades quickly though, and Malvina tries to write one more hit song before finally giving up and returning to Newton.

In April 1940 Nathanael West, then a contract writer at RKO Pictures, was asked to work on a script, tentatively named Malvina Swings It, which writer Charles Roberts failed to complete satisfactorily. After working on the screenplay for almost ten nonconsecutive weeks, West had turned it into Let's Make Music, which hoped to benefit from Bob Crosby's popularity. The rewriting was so significant West received solo screenwriting credit.^[1]

The reviewer from The New York Times commented that, "no doubt worse movies have been made," but was at a loss to name any. The Film Daily critic called it, "a picture for all situations, ages, and types, although it is conceivable that some inflexible devotees of classical music may be holdouts, and term it esthetically 'gross.' But it's plenty gross for the box offices."^[2]
