Query: The best "Making of a Musical" book ever-hands down

I have them all and I've read them all and (note the cost of the hardback in the Amazon pricing) this is the one I paid extra bucks for years ago on a search service-pre internet. The lessons about musical theatre construction are taught here in a way that makes them personal, fun and important to the reader; not unlike Moss Hart's education in playwrighting in "Act One". Explorations of when to reveal details about a character, how to construct a lyric and most especially the particular art of compression that drives a musical are a delight that simply never leaves the mind. And you will never hear the word 'spaz' the same way again. This is the book I have recommended about musical theatre more than any other and the one I have never (it is the rarest of the pack) lent out. "The Making of 'No No Nanette' is the dishiest-but this book, like the musical it describes is an act of joy and love.
