The Weisslers are loyal to their favorite performers on the show. Since Roxie and Velma are two of the roles that stand out, you'd think they'd find some new/different Roxies and Velmas. On the Roxie side, you have Bianca Marroquin (a bundle of energy plus extremely talented). She's currently on long term contract till March 2015. Ann Horak is one of the three Roxie understudies (in addition to Melissa Rae Mahon (who's on once in a blue moon and Tonya Wathen). The other long term Roxie is Amy Spanger, a Fosse veteran. On the Velma side, you have the two Velma understudies: Donna Marie Asbury (fantastic voice) and Stephanie Pope...longtime theatre veterans. I know that Velma is the veteran over Roxie, but depending on one person for the past 3 years or so for Velma causes a great deal of consternation among many Chicago fans.
"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)
