Jonathan Grafft and Nathan Johnson, and (clockwise from lower left) Mallory Park, Josh Wielenga, Sarah Ade Wallace, Andy Davis, Stan Weimer, and Jackie Skiles in Leading LadiesThursday's audience certainly enjoyed the Richmond Hill Barn Theatre's Leading Ladies, judging by their loud snorts and uninhibited guffaws. Ken Ludwig provides plenty of fodder for laughter, as do director Tom Vaccaro and his cast, who hit the comedy's high notes pitch-perfectly. As for me, I didn't just giggle but laughed heartily right along with the rest of the crowd at least a dozen times.
