Thanks, fleminec. I have the three ABC scores - if memory serves I got them through TehParadox; they've got a pretty big thread on the Star Wars music. Great to have another link to them, though.
And I agree with you on the old trading vines being superseded by the improvements in downloading. I must admit, once I found a bittorrent site for the group I was talking about (which, incidentally, was Genesis) I stopped acquiring my bootlegs through postal trades. It's so much simpler and quicker (but I do miss the anticipation of waiting for the postman to arrive with a bulky envelope!).
Sorry I can't help you with the vinyl rip for ROTJ. Good luck in finding it; I hope someone can sort that for you.
