Shayne will fill in for the vacationing Charlotte d'Amboise, who will take a break from the role of Roxie after the Dec. 12 performance. Shayne is scheduled to play the role of the merry murderess Dec. 13-Jan. 2, 2005. D'Amboise will then return to the Broadway company.

Tracy Shayne made her Broadway debut in the Tony-winning musical A Chorus Line. She also played Christine in Andrew Lloyd Webber's The Phantom of the Opera, and she succeeded Judy Kuhn in the role of Cosette in the Broadway company of Les Misérables. Shayne previously played the role of Chicago's Roxie Hart in April 2003 and again in June 2004.

Chicago — featuring a score by John Kander and the late Fred Ebb — currently stars Wayne Brady as Billy Flynn, Charlotte d'Amboise as Roxie Hart, Terra C. MacLeod as Velma Kelly, Anne L. Nathan as Matron Mama Morton, P.J. Benjamin as Amos Hart and R. Lowe as Mary Sunshine.

As previously announced, Tom Wopat will return to the role of Billy Flynn Dec. 7, and Ray Bokhour will assume the role of Amos Hart Jan. 10, 2005.

Chicago won the Tony 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.
