a topical show consisting of a series of scenes and episodes, usually having a central theme but not a dramatic plot, often with spoken verse and prose, sketches, songs, dances, ballet and specialty acts
A show that consists of disparate musical numbers, either by many different composers (e.g., Hey, Mr. Producer!) or by one individual or team (e.g., Louis Jordan, Five Guys Named Moe; Kander and Ebb, And the World Goes Round). What separates a revue from a plain old concert is the staging; the songs are performed rather than merely sung. Sometimes there might be a thematic thread running through some or all of the songs, but there is no overarching storyline.
A revue is a type of multi-act popular theatrical entertainment that combines music, dance and sketches. The revue has its roots in nineteenth-century American popular entertainment and melodrama, but grew into a substantial cultural presence of its own during its golden years from ca. 1916-1932. Though most famous for their visual spectacle, revues frequently satirized contemporary figures, news, or literature.
