Theater 2015-16: Paint still wet on its new name, Irish Theatre of Chicago expands to third play

19th in a series of season previews: Irish Theatre of Chicago took on its present name last season some 20 years after beginning life under the banner of Seanachai Theatre. Commencing its third decade with Geraldine Aron’s one-woman show “My Brilliant Divorce,” the rechristened Irish Theatre now spreads its wings by adding a third play to its season.
