I'm not exactly sure what was on Jessie's upload, but I found a pretty good copy of the complete score over at Chief Dundee. It's in flac, too.

I'm also checking out another so-called "complete" score. I'll let you know if it's any better than Dundee's.
EDIT: the other score I found was in-fact just the regular, official score, just renamed. For some reason it had 63 in the title (which made me think it had 63 tracks).
So, as of right now, Dundee's is the best complete version I've found.
