Hands down, the 1992 Austrailian cast recording, which isn't even the whole show!
I have met one or two of the cast members, and they are as bummed as I am about not having the whole thing in the can.
The opening strains of the overture simply chill/electrify me to the core and the following new orchestrations are the best, IMWO.
"Sticks and stones, sister. Here, have a Valium!"
