Following the Jan. 20 performance of the long-running, Tony-winning revival of Kander and Ebb's Chicago at the Ambassador Theatre, the show's original Amos Hart, Tony winner Joel Grey, will take part in a discussion and question-and-answer session. The Jan. 27 performance will be followed by a discussion with the show's current Roxie Hart, "Office" star Melora Hardin. (Hardin first participated in the "Talkback Tuesdays" series Jan. 6.)

Chicago's Tony-winning director, Walter Bobbie, will moderate the Jan. 20 talkback with actor Grey. Duncan Stewart, casting director for Chicago, will moderate the talkback with actress Hardin on Jan. 27.

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

Tickets for the Jan. 20 and 27 "Talkback Tuesdays" performance are available by calling (212) 239-6200 or by visiting www.telecharge.com.
