I think she's had an interesting rehearsal schedule, with the dance captain David Bushman working with her on the West Coast (possibly together with Leslie Stifleman). She probably has continued her rehearsal, up to now. I understand she had a "put-in" on Wed. Dec. 28. Bless those cast members who basically have to perform/practice the show with the new Roxie...on her first day. I hope there is some video of her playing some of the dances. When I saw the show on Dec. 25 and Dec. 27, you had the assistant conductor at the helm. I hope someone shares their experience of seeing Mel B.
"Noel [Coward] and I were in Paris once. Adjoining rooms, of course. One night, I felt mischievous, so I knocked on Noel's door, and he asked, 'Who is it?' I lowered my voice and said 'Hotel detective. Have you got a gentleman in your room?' He answered, 'Just a minute, I'll ask him.'" (Beatrice Lillie)
