Chicago is a 1975 American musical with music by John Kander, lyrics by Fred Ebb, and book by Ebb and Bob Fosse. Set in Chicago in the jazz age, the musical is based on a 1926 play of the same title by reporter Maurine Dallas Watkins, about actual criminals and crimes on which she reported. The story is a satire on corruption in the administration of criminal justice and the concept of the "celebrity criminal".
