Time’s running out to see the gang of limp-wristed actors known as GayCo in their first-ever holiday show, Do You Fear What I Fear? The musical revue pits lesbians against circuit boys, and the baby Jesus against—well, you’ll have to see for yourself. The six-person cast, directed by stellar token straight guy Jim Zulevic, rips through such hot numbers as ‘I’m Not Committing Suicide for Christmas,’ ‘I’m Putting the Ex Back in Xmas’ and ‘Elegy for Fields,’ satirically marking the metamorphosis of Marshall Field’s into Macy’s. Well, at least they can keep the ‘M.’ Through Dec. 17 only; Friday and Saturday, 10:30 p.m., Bailiwick Repertory; (773) 883-1090; $15.
