unofficial alternate system. This is the problem, there is no set schedule for the standbys like there are with most other shows. Most standbys will do matinees, but for Wicked they just do random performances. The whole "vocally demanding" thing is not an excuse, because, as I said, there are plenty of roles out there that are just as, or more, vocally demanding. I just don't get why Wicked feels it can put standbys in whenever, and it appears, quite frequently.
