Following the Sept. 8 performance of the long-running, Tony-winning revival of Kander and Ebb's Chicago at the Ambassador Theatre, longtime Chicago dance captains Gregory Butler and Gabriela Garcia will take part in a discussion and question-and-answer session.

The conversation will be moderated by casting director Duncan Stewart.

"Talkback Tuesdays" will also be broadcast online for live interactive viewing at www.ustream.tv/channel/chicago-the-musical. The broadcast will begin at approximately 10:30 PM ET. During the talkback, online viewers may submit their own questions through the Chicago feed on Twitter (www.twitter.com/chicagomusical).

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