This early talkie antique is a backstage musical from Warner Bros. The plot involves the out-of-town tryout of a new musical comedy, and the people who perform therein: a bitchy leading lady (Betty Compson), an arrogant comedy lead (Joe E. Brown), and a starstruck chorus kid (Sally O'Neil). At the very last moment, the leading lady refuses to go on, forcing the producer to put the chorus girl in her place. It turns out that the star's seemingly rotten behavior was deliberately designed to give the chorine her big break. In between several Technicolor musical numbers (now only existing in black-and-white), we hear a lot of pedantic talk about "the show business." On with the Show's sole virtue is the exquisite Ethel Waters, who introduces her hit song "Am I Blue?"
