I just got a single ticket in row P center orchestra for next Sunday's matinee, so it's not totally sold out. I imagine they have mostly scattered singles at this point especially for the weekends. They haven't done much advertising because the remaining seats will probably get scooped up after the reviews come out.
For folks familiar with the Wortham Center, Audra's shows are in the Cullen Theatre wihich is the smaller of the 2 theaters in the center. I think it holds around 1400 people. There's not a bad seat in the house.
