The West End production of Chicago opened at the Adelphi Theatre Nov. 18, 1997. It transferred to the Cambridge Theatre in April 2006.

Chicago, which is based on the play by Maurine Dallas Watkins, features a score by John Kander and Fred Ebb with a book by Ebb and Bob Fosse. The production was choreographed by Ann Reinking in the style of Fosse; Walter Bobbie directed. In fact, the West End production was staged by the entire creative team of the Tony-winning Broadway revival, which continues to play New York's Ambassador Theatre.

Chicago is produced in London by Broadway producers Barry and Fran Weissler.
