Fiasco's Into The Woods sheet music?

Hi all -

I was wondering if anyone is aware of a place where I could find/purchase a copy of the arrangements which Fiasco used for their Into The Woods. I found the arrangements to be fresh and beautiful and would love to get my hands on a copy of the score.

I realize that it being a relatively small off-Broadway production, it may not be available (it certainly hasn't been released commercially in the way that many shows put out a vocal/piano selections book) but I wanted to reach out and see if anyone knows of something. I'm not asking for anyone to give me a way to download/obtain it illegally, I am more than willing to purchase it from a reputable source if available. I know that this is a long shot, but you never know if you don't try.

Thanks!

an illegal copy is probably you're only bet (if it exists out there)
