Hello Flash Jazz,
People tend to say that the earlier EMI releases sounded very mudded, I never heard this mudded or muffled sound. However, when the Hollywood Record appeared in 1991 I was vey impressed by the improved sound. Also a good choice could be the Japanes Toshiba release. But to this event I still listen and enjoy my Hollywood Recors release! Who knows maybe we get an extended and remaster (triple version) by Universal, but I won't hold my breath for it, if I were you.
Cheers, Tom
