I had the honor of reading the screenplay version and a draft of the novel-in-progress and commenting on it. Later, Vonda thanked me in the book's acknowledgments -- I've been thanked in many books for editorial assistance, but that was the first time anyone ever thanked me for providing musical help!

I didn't know that! That's wonderful. (Indeed, there you are. Congratulations!) In an ideal world, you could consult on music for the film.

I've always wanted to read the screenplay; it's one of the few books I've read and thought I would prefer—as originally intended, apparently—as a film. How does it differ from the finished book?
