After some research, it seems that there are 2 laserdisc releases for The Golden Voyage of Sinbad – one by Pioneer and another by RCA/Columbia. It seems that the Pioneer one is the best.
The Pioneer Special Edition laserdisc has an isolated music track and possibly a stereo mix (whereas the DVD only has mono).
( Catalog Number PSE91-20 ) (1.33:1) (3 Sides) (CLV+CAV) (CC) (NTSC)
It would be nice to have this preserved as the later Columbia DVD releases also have some digital editing.
