Sadly not the 1939 James Stewart comedy/thriller, but an anxious-to-please British musical comedy from director Val Guest. Set in the era before the advent of rock 'n' roll, the film follows the fortunes of composers Terence Morgan and George Cole, who, tired of being rejected in favour of more trendy music, pin their hopes of success on re-jigging a popular song. The music is not to everyone's taste, with Mylene Nicole's performance with Ted Heath's band striking the lowest note of all.

Two aspiring songwriters finally manage to sell a tune by claiming that it was composed by a reclusive musical genius. When the tune hits the top of the charts, they find themselves having to produce the "real" composer.
