The 1995 laserdisc was made by the same company as the 1997 DVD, which is my source for audio. The audio was stretched to 5.1, but I compressed it down to mono using Handbrake. Sadly, it’s as close as I’m gonna get for now.
I have read that the 1997 Live DVD is basically the mono audio with some added sound effects to make it 5.1. I wonder if the effects are on separate tracks from the main audio?
