I also remember an oversize hardbound edition.
Look it up on www.abebooks.com and see if there are some used copies out there.
Then add abebooks.com to your favorites list because when you need a book check that site even before Amazon.
Edit: I'm mistaken. The book I am thinking of does not contain the script. From the description it sounds like a history of the show, but not the script.
On the other hand it could be a source in writing the actual paper. The copies are cheap--under $4 and no shipping for some.
