Following the Oct. 28 performance of the long-running, Tony-winning revival of Kander and Ebb's Chicago at the Ambassador Theatre, five-time Tony-winning costume designer William Ivey Long will take part in a discussion and question-and-answer session.

The series, according to press notes, is designed to "provide theatregoers with an exclusive, behind-the-scenes glimpse into the world of Chicago."

William Ivey Long is currently represented on Broadway with his costume designs for Chicago, Hairspray and Young Frankenstein. He received Best Costume Design Tony Awards for Nine, Crazy for You, The Producers, Hairspray and Grey Gardens. This season, his designs will be seen in the revival of Pal Joey and the new musical 9 to 5.

Chicago currently stars Michelle DeJean as Roxie Hart (through Nov. 2), Terra C. MacLeod as Velma Kelly, Raymond Bokhour as Amos Hart and Carol Woods as Matron "Mama" Morton. Charlotte d'Amboise will return to the role of merry murderess Roxie Hart Nov. 3.

Tickets for the Oct. 28 "Talkback Tuesdays" performance are available by calling (212) 239-6200 or by visiting www.telecharge.com. The Ambassador Theatre is located in Manhattan at 219 West 49th Street.
