Grey Gardens, on broadway
Here's a show with a plot that is quite unusual, set as a musical, on Broadway. I enjoyed it immensely -- recommended! Christine Ebersole is the lead, she briefly was a regular on Saturday Night Live (early eighties, for a couple of years) - not that I remember her from then although from the un-made-up photo on the web site, I kind of recognize her. Read more about it on wikipedia (where else?)
p.s. The whole web site is made in flash and as a result I can't link to any of the inner pages. Not smart!
