Turn off the moon (1937)

Department store owner J. Elliott Dinwiddy has waited fifteen years for the perfect astrological moment to propose to his secretary, Myrtle Tweep. His astrological advisor, Dr. Wakefield, has told him that if he can unite a boy and a girl in true love before midnight, he can propose to Myrtle the following night. Fate then brings unemployed dancer Caroline Wilson into the music department of Dinwiddy's, where she meets handsome songwriter Terry Keith.
