I don't know. Sorry.
And yes, that is the ESB with the nice LP-sized full colour booklet and... the poster. I don't really know how good it is, I haven't listened to it for years. I got it second hand myself. I was exhilirated when I found it. In those days there weren't many soundtracks available in Holland.
Exactly, and they change edits. In fact they usually make a separate recording for the album, although I'm not sure if they did that with Star Wars.
But I have no record playern connected right now, I'll have to find the copy on a cassette to check it out. That may take some time though, and I don't know if I'll get to do it at all really. But I'll try.
