glad you enjoy them heh
As for a book, I have decided to start compiling my information on a website... I don't have much experience building websites so it's a simple geocities site... but I'm only working on the outline at the moment. Unfortunately/fortunately, there is so much information that even having separate pages for the individual films isn't enough. There will probably be 3-5 pages for each film score lol....
If you're interested, here's a very very rough idea of it: Star Wars Music
EDIT: Normally there would me a music track playing but with my upload place down, you won't hear it.
