I went on a similar tour back in 1983 or 1984. It wasn't the same as yours, though. Mine was geared towards "entertainment" and was only for kids. We were taken backstage and while I don't remember much, I do remember that we got a book to take home. It is about 11x11 and it has a pink, hard cover. I will see if I can dig it out anywhere and get some more info on it. I know I still have it. I will have to poke around in my attic.
