Today, the great J.W. Rinzler posted a 56-page PDF on his website of the final chapter of his Making of Episode III book.http://www.jwrinzler.com/uploads/3/4/4/6/3446315/the_final_chapter.pdf
Great stuff in here about the making of the score in addition to the final effects run-up to the release of Revenge of the Sith.
This PDF was available on starwars.com for a while, but it got lost in Internet hell and has been unavailable until Mr. Rinzler's most recent twitter post. Hope all of you enjoy this as much as I do.
