Think you’ve got what it takes to be a playwright? Prove it. Tonight, 7pm, at the Baruch Performing Arts Center (25th St between Lexington and Third Aves), come hear a free reading of Ann Marie Healy’s Seven Stars as part of the MCC’s Playlab series. If you still feel you can contribute something to her work-in-progress story of mundane middle-class disappointments and lives that slowly slip away, you can tell her all about it during the ensuing reception. We suggest swilling copious quantities of free wine first, though, because playwrights tend to be really good drinkers. (Ever notice how almost every play has at least one character who just drinks the whole time?) RSVP recommended.
