Opening: One of the nation's most durable community theater companies, Theatre in the Round concludes its 60th season with a production of "Round and Round the Garden," a comedy of affections and affectations by British wit Alan Ayckbourn. Set in a country house, the play revolves around a despotic invalid and her love-seeking, caretaker daughter. "Garden" is part of an Ayckbourn trilogy called "The Norman Conquests." Like a comic "Rashomon," all three plays -- "Table Manners" and "Living Together" are the other two -- look at the same events of one weekend from different spaces. "Table Manners" offers the view from the dining room. "Living Together" shows things from the sitting room. And "Garden" is like eavesdropping on some nutty people from the outdoors. John Gaspard directs a cast that features Muriel J. Bonertz, John Adler, Amy Shomshak, Kelli Gorr and Rick Lamers. (8 p.m. Fri.-Sat., 2 p.m. next Sun. Ends July 29. Theatre in the Round, 245 Cedar Av. S., Mpls. $22. 612-333-3010.)ROHAN PRESTON
