Chicago should be over between 9:20-9:30 and since it's right around the corner from the Gershwin, I'm sure Brooke will be able to get there before the concert is over. I imagine it would run about two hours.
I hope she doesn't miss the show, as I think Charlotte is the standby now, and I want to see her perform at the benefit! (Hopefully she will do something other than a Roxie number...)
