1991 MGM LaserDisc [ML101418]: Excellent sound. I really can't imagine a mono soundtrack from 1973 sounding much better than this. There's hardly any hiss or distortion, so it's bizarre that later editions go so aggressively to remove what little is here. The analogue track is the same mastering, but reportedly has a few dropouts.
1993 Japanese MGM LaserDisc [NJEL-52733]: Identical to the 1991 MGM LD.
1993 MGM LaserDisc [ML10480]: Identical to the 1991 MGM LD.
1995 MGM HiFi VHS: Very aggressively noise-gated and bass-boosted. Horrible.
1999 R1 MGM SE DVD: Significant noise reduction compared to the MGM LaserDiscs.
2008 MGM BD: Like the SE DVD but with further bass attenuation.
