I was disappointed in the management of the rehearsal. No announcement. No hand-out to tell us who was dancing, like they do at both NYCB and ABT. I saw a lot of people with audio sets, but have no idea where those came from or what they were hearing. They weren't handing them out as you walked into the theater.
They usually hand those out in a booth in the Hall of States. However, while I wasn't there, the commentary is usually on a casual fan's level, so you may not have missed much.
