The cast of the recent Upstart Arts production of “The Importance of Being Earnest” comes together one more time for an encore performance of Act 2. Come see one of the funniest pieces of theater in the English language as two men who want to be Earnest Worthing, two women who want to marry Earnest Worthing, a talkative canon, a governess with strict views and, of course, the butler war over tea, love and muffins.
