There are a few musicals that simply cry out “BROADWAY” at their very mention and, inarguably, Chicago is one of them. The original production of the John Kander, Fred Ebb, and Bob Fosse musical goes back 50 years to 1975, enjoying a New York run of 936 performances. A 1996 revival production of Chicago is still running on Broadway with more than 11,000 performances under its belt. That revival production with direction by Walter Bobbie and choreography by Ann Reinking (after Bob Fosse’s original choreography) has also spawned a number of National Tours, including the current one that is making a stop in Knoxville this week at the Tennessee Theatre for eight performances through Sunday, February 16.
