The best moment in GayCo Productions' first holiday revue is tender, not funny: Andy Eninger plays a lonely gay man and Judy Fabjance the female prostitute he brings home just because he wants to be nice to someone. Other sketches blend zinging humor with amusing snapshots of complicated gay lives. Still, there's less political material than in previous shows--unless you count a funny, on-target song about the passing of Marshall Field's--and much of the show could use cutting and rearranging from director Jim Zulevic as well as more energy from the cast. A lot of the good stuff here is hidden. Through 12/17: Fri-Sat 10:30 PM, Bailiwick Repertory, Bailiwick Arts Center, 1229 W. Belmont, 773-883-1090, $15.
