The new iO Chicago Theater in the Clybourn Corridor has announced its full roster for its grand opening weekend Aug. 29 and 30, and it’ll bring back a celebrity-filled lineup of Chicago improv alumni. As reported earlier in the Tribune, performers will include "30 Rock’s" Jack McBrayer and Scott Adsit, "Saturday Night Live’s" Tim Meadows and David Koechner, and new "The Daily Show" correspondent Jordan Klepper.

The official grand re-opening will take place five weeks after iO closed the doors at its longtime Wrigleyville location at 3541 N. Clark St. Tickets for these one-off shows are $35-$50 and will likely sell out quickly. The full lineup can be found on iO’s website.
