Conrad Nagel, representing the Hollywood movie community, and Jack Benny, representing the Broadway stage community, act as the interlocutors of a musical comedy revue. A plethora of chorus boys and girls are featured front and center in some of the song and dance numbers, and provide back-up to some other acts. But the revue primarily is a vehicle to highlight a cavalcade of Hollywood movie and Broadway stage stars. One early running gag has both Nagel and Benny playing straight man to Cliff Edwards, who just wants a nice introduction to his act. Edwards would return later to be featured along with the Brox Sisters in one of the highlights of the second act, a production number around the song "Singin' in Rain", complete with rain soaked stage. A reprise of the song with the entire cast acts as the revue's finale.
