If the shows creators think that this show could have a life in regional theatre, they could possibly shop around and see if anyone will invest in a recording (but not necessisarily with the original cast), and possibly mail-order it via a web site.
I know this was done with a DC production of Eleanor (the Eleanor Roosevelt musical. Soooooo much fun doing that show...

). Getting some sort of recording out might help it have some legs regionally.
And it wouldn't probably be too expensive to pay people, as there were four characters and a small band.
Still, I'd rather see a Cry-Baby CD first, but that's just me.
Xanadu! Can't cry on cue!
