Writer-performer Tim O’Malley’s honest, funny show about his life as an alcoholic and drug addict has been running off and on since last April. One wonders if the primary audience has been people in recovery and those who love them–but if so it’s time for the word to spread. O’Malley’s observations about the costs of his habits and the benefits of changing them aren’t earthshaking, but his generosity of spirit is worthy of attention and respect. A onetime member of the Second City main-stage company, O’Malley recounts the past ten years in quick bare-stage scenes, supported by four able cast members and the occasional silly hat or feather boa. Like any good sketch-comedy revue, Godshow has evolved: since its performances nine months ago, bits have been added, subtracted, or reshuffled. (I’m glad, though, that O’Malley continues to describe Ireland as “the Disneyland of drinking.”) Norm Holly’s brisk staging dodges sentimentality without sacrificing emotion. The Second City E.T.C., Piper’s Alley, 1608 N. Wells, 312-337-3992 or 877-778-4707. Through February 25: Wednesdays, 8:30 PM. $10.
