Mandalay Bay was my second time seeing "Chicago" (out of four times).
It was the full show (not a 90 minute pared down version), but I can't remember if the "Poker sequence" was cut yet or not. I know by the third time I saw it (when it toured back to Seattle), it was gone (as I got to the end of the show and said out loud "Hey! Where's the poker scene???"). I think it may still have been in the show at this point.
I saw it with Marilu Henner (who was a lot better, and more gracious stage dooring afterward than I expected), Mamie Duncan Gibbs as Velma (I think Brenda Braxton just left the week before, but I didn't really mind as Mamie was EXCELLENT!!! She is such a sweetheart! I love her!!!), and Ben Vereen (who was Ben Vereen...).
Xanadu! Can't cry on cue!
