Delight (or at least distract) your audience for a short while (never more than forty-five minutes!) with an approximation of a love story. Your love story should star a likable young couple who can tap-dance and sing, but who are kept apart from each other’s arms by a villain—often a banker, sometimes a gangster (same idea, different costume)—who gnashes his teeth and tries to destroy our good couple. There should be a floozy with a notable bustline making eyes at our hero—but the hero must only have eyes for his one true girl. There should be a handsome swain who tries to woo the girl away from her fellow. There should be a drunken hobo character for comic relief—his stubble indicated by application of burnt cork. The show always had at least one dreamy ballad, usually rhyming the word “moon” with the word “swoon.” And there was always a kick line at the end.
