Playing now at the Orpheum Theater is the newest touring production of Chicago, direct from Broadway. The cast includes J. Peterman himself, John O'Hurley in the role of attorney Billy Flynn, and a pair of incredible dancers/triple-threats, Bianca Marroquin and Terra C. McLeod as Roxie Hart and Velma Kelly, respectively.

This latest touring production arrives in San Francisco, playing through November 16, just as the Broadway production is about to become the second longest-running show in Broadway history, surpassing Cats. Chicago opened in its current revival in 1996, and has been running 18 years straight, with nearly 7,500 performances.

The touring ensemble also includes a group of fantastic dancers who carry this intense dancing musical on their backs and thighs, literally. And unlike in the Oscar-winning 2002 movie musical, you really get an appreciation for how hard, and impressive, this kind of dancing is watching this crew slither and tango through each and every number.

Tomorrow, Tuesday, November 11, I'll be live-tweeting from backstage at the Orpheum, just to give you a glimpse of what a Broadway musical looks like from back there — and trying not to get trampled as the dancers run on and off stage.

This will all be starting around 7:30 p.m. on SFist's Twitter, so please follow us if you don't already. (And I'll be posting stuff to our Facebook page as well.)
