There is one off-Broadway musical I have been curious about for years, and if anyone has an old soundboard recording, you'd be my favorite person. It was called SMITH and it starred Don Murray as a man whose life kept turning into a musical. The reason it has intrigued me is that IIRC it was rather successful off-Broadway and it shuttered for a few weeks with the intention of moving to Broadway (it never reopened, not sure why). I was a kid in NYC during those few weeks and one of my Uncles knew someone either in or with (as in producing) the show and I had a standing invitation to come down and see them rehearse, which like an idiot, I didn't do. I've wondered about that show ever since.
