Arena Stage is tickling our fancy with a special evening geared to the LGBT community, with ticket prices reduced to $50 and a post-show piano bar with the cast. Yes, it's good to be gay. The show in question: Oklahoma! Arena snagged four Helen Hayes Awards, including Outstanding Musical, this year for its production, which it's reprised during what used to be the theater summer doldrums. This Wednesday, Aug. 17, at 7:30 p.m. The Fichandler at Arena Stage, 1101 6th St. SW. Tickets are automatically discounted by using the promo code OUT50 when you order online or by phone at 202-554-9066.
