Grey Ghost Theatre is a new theater company—its inaugural show, Sarah Ruhl's Melancholy Play, kicks off tonight at 7:30 PM at the Viaduct Theater (3111 N. Western). Why single Grey Ghost out of all the new theater groups in the city? Because they got a new Meat Loaf cover band to play a fund-raiser for them at Cole's (2338 N. Milwaukee) following the performance.
