MGM had hopes of turning Metropolitan opera singer Lawrence Tibbett into a movie star, but Cuban Love Song brought this two-year project to an end. Tibbett plays a cocky marine stationed in Havana, who devotes his attention to voluptuous Cuban peanut vendor Lupe Velez. He serenades her with "The Peanut Song" several times in the course of the film, and Velez falls madly in love. But Tibbett is the "love 'em and leave 'em" type, and when World War One breaks out he drops Velez like a hot tamale and heads for Europe. Ten years pass: Tibbett returns to Cuba, only to discover that Velez has died...and then he meets a cute 9-year-old "orphan" boy whose favorite tune is "The Peanut Song". Cuban Love Song is highlighted by an uproariously graphic "castor oil" gag involving supporting actor Jimmy Durante.
