Yes. I was always sad that it was not actually complete. It all made more sense when I saw the show. It's strange to think of how the show changed over time: book and music, and now even costumes, as I understand it.

I had the full original London cast recording on tape and on vinyl. ^_^ The libretto booklet couldn't be included with the cassette, so you could get the libretto free by mailing a request. I got extras for my POTO friends; it was great.
