Thanks, miliosr. The Wikipedia entry sounds as if it was written by a fan or fans, certainly, not unusual on Wikipedia, and the information sounds quite believable. Sounds a tad self-defeating, but it's her call. Has anyone else read or heard something?
Dean has been very protective of her work, and from time to time has wanted to rescind permissions for performances. This time around, according to a colleague who has staged her work in the past, I believe she has indeed closed the door, though I do not know if it will remain closed.
It's certainly her call if she wants to do it, but I truly hope it doesn't end like this. I would hate to see those works lost to future audiences.
