Jane Chambers' play "Last Summer at Bluefish Cove" is about a group of lesbian friends and lovers who vacation each year at the same idyllic Long Island beach colony. First staged in 1980, it is not an exercise in political advocacy, although it does poke fun at one character, a renowned feminist writer who refuses to come out of the closet lest she jeopardize her fame and fortune. Mainly, it is a warm-hearted, sepia-toned look at the eternal search for love, authenticity and steadfast friendship.* "Last Summer at Bluefish Cove," Vanguard Theatre Ensemble, 699-A S. State College Blvd., Fullerton. Fridays and Saturdays, 8 p.m.; Sundays, 5 p.m. Ends July 21. $15. Student rush tickets, $5. (714) 526-8007.
