"The show must go on" is a well-known phrase in show business, meaning that regardless of what happens (such as the lead performer breaking a leg), the show must still be put on for the waiting patrons. Theatre veteran Noel Coward queried this cliche in the early 1950s, though, writing a song with the title "Why Must the Show Go On?" The Show Must Go On may also refer to:
