The P&S Dolby mix needs to be preserved. The only problem is that it was only ever released in the U.S. in analog. (There isn't even an LDDB listing for a stealth digital re-pressing, like they have for that supposed PCM issue of Grease that SilverWook and I could never actually find a copy of.)
Already done (at least the analog part). I did a rip a couple years ago of the analog soundtrack from this LD:

since there were rumors the letterbox soundtrack was changed.
