This week Mortified celebrates 6 years, the Sing-Along Nutcracker hits YBCA and Celtic Yuletide brings a bit of Irish holiday spirit via song and dance. 

After years of sold-out shows, this Friday Mortified celebrates their 6th Anniversary at DNA Lounge. This round of hilarious, deftly honest performances will be a round-up with the Best of 2011.

For a more interactive evening, and holiday experience, take part in the 2011 Dance-Along Nutcracker, this Saturday and Sunday at YBCA. The concept is simple: the SF Lesbian/Gay Freedom Band pays and you dance — along with the Rat King, Clara Flowerchild and Sgt. Lemon-Pepper Nutcraker, of course!

Starting Tuesday, step to a little Irish jig with Celtic Yuletide‘s holiday show at Marines Memorial Theatre. The show runs through January 1 and will star Irish Tenor Michael Londra, the lead singer of Riverdance on Broadway.
