I was in the audience on Friday night. I was surprised she did all the dancing. I would have expected her walking through or off to the side during the dance pieces. I thought, I assume she knows her limits.
The intermission seemed long, and I was thinking how I she has always performed in the shows I have seen her in over the years (meaning no understudies). But, I was not shocked to hear she was out for Act 2. I really hope she is okay.
As for the understudy, Darlesia Cearcy was very good. I closed my eyes a few times and she sounds similar to Audra. Very strong and beautiful voice. Her only disadvantage was not playing Act 1 and establishing herself, but I am so glad I got to see Act 1 with Audra. What an embarrassment of riches this show has with its performers. Think about it, Audra is only one of 5 top-tier performers. Then you have the incredible supporting players, and chorus. There is a lot of talent on that stage.
