• Oakland Interfaith Gospel Ensemble: This awe-inspiring gospel ensemble from "the other side of the Bay," noted for its "interfaith, multi-racial, and multi-cultural" makeup -- will get you in the mood. The Christmas-y mood, that is. And if you can't handle all of the holiday joy abounding, there are plenty of bars around the neighborhood where you can get your joy on, booze-wise.

    The singing starts at 7 p.m. and 9 p.m. at Slim's; $15.

  • Midnight Mass at Grace Cathedral: Atone! Or whatever one does at a Catholic Mass an Anglican service. Anyway, we hear it's a very pretty party, if you will--lots of candles and singing and Eucharist-ness and stuff.

    Jesus Christ stops by to say "what up, dude?" starting at 11 p.m. at Grace Cathedral; free.

  • San Francisco Gay Men’s Chorus: Come hear San Francisco's all-male chorus -- a choir rife with homosexuality! -- featuring "such beloved traditions as the popular sing-along, the Hallelujah Chorus, music from many faiths and cultures, and "kids" of all ages" having their pictures taken on Santa's knee. Hot. Also, KRON 4's Jan Wahl makes a special guest appearance.

    The harmonizing starts at 7 p.m. and 9 p.m. at the Castro Theatre; $17-30.

  • Chicken John's "A Chaos Christmas Carol": Former San Francisco mayoral candidate makes a triumphant return with this might of "yuletide madness." According to 12 Galaxies: Chicken John started a tradition. Family holiday for people without families. On Christmas Eve, no one should be alone. So he threw a show. Here’s how it works: everyone brings a stupid gift or two, and puts it under the tree. Chicken hosts a game show that everyone in the club plays for like 3 minutes. Everyone wins. You open the gift that you select for winning right there on stage. When we run out of gifts, the show is over. Last year the show was 3 1/2 hours long. It was either the greatest thing anyone has ever seen or the worst show on Earth. This year promises to be worst." And there you have it.

    The zaniness starts at 9 p.m. at 12 Galaxies; $8.
