That's a great site, but that bit of information is incorrect. What I've seen referred to as the '85 remix actually appears on the '84 VHS. Do you have the '84 VHS tape? If so, give it a listen.
But since you're looking for the straight Dolby Stereo mix, the '85 CAV LD that someone mentioned earlier may be the best choice. I don't have that disc myself so I can't verify the sound mix.
