mangobyebye,
Here's a first one: a comparison between the Mynock Cave track session (that matches with the film speed and pitch), and the original SE track that I've sped up to a factor of 4... The BBC recording looks even faster:
Ooops, sorry for the double link, here's also the new edit for Mynock Cave with the RSO CD (a little faster than the original SE): Mynocks Optimum (new)
Also, maybe - if you don't know the RSO LP's - You could check the blue link from my signature and grab the LP's transfers I'm using for my edit. If you say the pitch is correct on the LP's I'd be amazed (and would have some big work to do). Oh, and I'd recommend you listen what I've done with the 1977 SW...
And if any of these recordings really match or look convincing... Oh boy, I won't touch anything. Too hasardous, and I feel something is wrong when I touch this anyway.

EDIT: I've just compared two tracks:
-The Rebels Escape: the C.Gerhardt recording looks to have the same pitch than the RSO LP transfer. The Anthology version isn't that low however, but a little lower.
- Main Title: The RSO LP transfer is a little faster than the RSO CD, of almost nothing.
Also, as said before you may check "Hyperspace" on CD2 wich is at the same speed than the LP.
Thanks for your help, all this looks like a big headache.
