Dirty Little Showtunes. What if Riff and Tony borrowed 'Nardo from Anita?" Either you get that reference or you don't — and if you don't, then you might consider skipping Dirty Little Showtunes. But if you have even a cursory knowledge of shows like West Side Story, and if you have a high tolerance for quips about every possible flavor of gay sex, then you should have a great time at this extravagantly clever revue. Conceived and directed by F. Allen Sawyer, with unusually sharp lyrics by Tom Orr, Dirty Little Showtunes manages to give nods to gay adoption, gay marriage, gay sluts, aging, leather daddies, drag queens, bears, STDs, and HIV meds over the course of two fast-moving hours. First produced in 1997, the show returns to New Conservatory with some of its original cast members, along with parodies of songs from recent Broadway hits like Hairspray and Wicked. But the heart of the show remains its loving send-ups of chestnuts from The Pirates of Penzance, Anything Goes, and Sweet Charity, with all of the lyrics rewritten to be genuinely filthy. Featuring a game energetic cast and a superabundance of wit, this is one revue that doesn't feel like a rehash. Through Jan. 29 at New Conservatory Theatre Center, 25 Van Ness (at Market), S.F. $24-$40; 861-8972 or www.nctcsf.org. (Chris Jensen) Reviewed Jan. 12.
Three Viewings. You walk into a chapel, you sit, and when the lights go out, you listen to three grieving people — one at a time — tell you how the person they loved most died and what they did to go on afterward. It's a powerful way to spend an evening, especially since Three Viewings, a series of interlocking monologues produced by Theatre Anew, is at its best when its protagonists are at their worst — their most lost, their most uncertain, their most confused before the undeniable silence of the grave. Jeffrey Hatcher's script is unconvincing when describing people's ordinary lives, but his characters grab you by the throat when they move out of their comfort zones. Diane Bailey (who also directed) is a standout in the final monologue, and the setting — the play takes place in the beautiful Presidio Chapel — is better than any set design could be. Three Viewings is short, about 90 minutes, and few moments are wasted. The characters may not know how to make the most of their time on earth, but the show — the only thing that must go on — knows exactly what it's doing. Through Jan. 29 at the Presidio Chapel, 130 Fisher, S.F. $15-$45; www.theatreanew.com. (Benjamin Wachs) Reviewed Jan. 12.
