Bedlam Theater is community theater in the literal sense — a community of actors, directors and playwrights just as apt to be serving beer or cleaning the bathrooms as performing on stage. Two of those people have written and directed two new, short works in an evening Bedlam is calling Dali Dada — on stage through May 2. After that, Reich’s Dali’s Liquid Ladies goes on a two-week tour by van.
