NYC's longest-running comedy revue, Chicago City Limits, has begun performances of its newest show, Y2K, You're OK, for a planned official opening Aug. 4 at their home space (First Ave at 61st Street).

The production takes a satiric look at mankind's achievements, failures and follies of the past 1000 years, from the Crusades to contemporary times, showing us that for all the differences things still stay the same.

The troupe was formed in Chicago in 1977 by George Todisco and other performers in workshop at Chicago's legendary Second City. Todisco, who died in 1981, served as artistic director and producer for the troupe during its early years. After moving to Manhattan a year later, the group began appearing in nightspots and comedy clubs, eventually moving Off Broadway (1980) to the Jan Hus Playhouse and, currently, their own theatre (on First Ave. and 61st St. in New York). For 15 years and counting the troupe has also been offering workshops in improvisational theatre for both beginners and seasoned performers.

The cast includes: Joe DiGise II, Carl Kissin, Denny Seigel, and Victor Varando.

Previous Chicago City Limits titles have included: CCL With Clam Sauce; He She And It; X The Roman Numeral; Scandals Of `89; Saddam You're Rockin' The Boat; The Official Comedy Team Of The 1992 Olympics; Lame Duck Soup and Let Loose The Dogs Of Improv.
