The revival of Chicago began life as one of the three annual Encores! presentations offered by City Center. The musical opened on Broadway at the Richard Rodgers Theatre in November 1996 where it remained through February 1997. The musical transferred to the Shubert Theatre on Feb. 11, 1997, and played that house through Jan. 26, 2003. The revival reopened at the Ambassador Theatre, its current home, on Jan. 29, 2003. Read more about the revival in the Playbill Vault.

Chicago won the Tony Award for Best Revival of a Musical in 1997 as well as awards for actors Bebe Neuwirth and James Naughton, director Walter Bobbie, lighting designer Ken Billington and choreographer Ann Reinking. The original production was directed and choreographed by the late Bob Fosse. The modern classic has music by John Kander, lyrics by Fred Ebb and book by Ebb and Fosse.

The Ambassador Theatre is located at 219 West 49th Street.
