Not since Judy met the boy next door in St. Louis has there been a heaping of tuneful, romantic Midwestern American life like this! Doris Day and Gordon MacRae team for spoonin', croonin' and swoonin' On Moonlight Bay, based on Booth Tarkington's Penrod stories. "Try not to walk like a first baseman," Mama (Rosemary DeCamp) tells tomboy Marjorie (Day) as she prepares to date college man Bill (MacRae). The advice takes. The lovebirds hear wedding bells ahead, just as soon as Bill gets his sheepskin. But World War I rages "over there." And Papa (Leon Ames) rages at home after a flap with his prospective son-in-law. Will harmony return to this Hoosier home? Surely Day and MacRae will make musical harmony. And On Moonlight Bay will have you sailing along.
