I haven't seen Patti Murin play Sharpay but I have seen her in other roles and I love her voice, but I still enjoyed Chandra's performance on tour, although the role seems to be written as more nasty than before.
That makes sense about the swings. I knew that some of them were onstage every night (I think Leonard Sullivan is considered a swing as well), didn't know if they all were. I figured if they were covering someone, they would do both their own role and someone else's, not cutting their own. The All Shook Up tour and 42nd St had performing/partial swings as well.
Dean: Can I tell you something?
Lorraine: That depends on what it is.
Dean: I think you're really really pretty.
Lorraine: (after a pause) Ok, you can tell me that.
