I can't remember if I was still working for the New York State Theatre Institute (NYSTI) after I discovered HHW in 2004, but between 1994 and 2004, I did two shows for them, A Tale of Cinderella while got a recording and DVD and a NY State tour, The Snow Queen, and Magna Carta. Around 2007 or so, the company folded amidst a lot of nasty allegations that hurt friends of mine who worked with the Institute.
My friend Patricia di Benedetto Snyder, who founded the company and ran it until its demise, has written a lavish history, jampacked with wonderful photos of productions and posters, and she sent me a copy this week. It's huge, it weighs a ton, and I'm having a great time just browsing though it. When I have more time in the next few weeks, I will actually read it.
