The Santa Susana Repertory Company's version of the long-running off-Broadway hit "The Fantasticks" will conclude its run at the Civic Arts Plaza Forum Theatre, 2100 E. Thousand Oaks Blvd., Thousand Oaks. As with most Santa Susana productions, the cast features performers that TV soap opera fans will recognize--including Sabrina Lu from "The Young and the Restless" as Luisa. A blend of whimsy and romance, the show is a musical fantasy about a boy and a girl whose fathers pretend to feud in hopes their children will fall in love. Show times: 8:30 p.m. Friday and Saturday, 2:30 p.m. Sunday. Tickets: $25, $22 senior citizens and students; group rates. Information: 684-6035 or 497-8616.
