This short, swift read chronicles the birth of the classic musical, The Music Man, from conception to its opening night on Broadway in 1957. The book's most interesting parts are those that highlight Wilson's ethic at work in the show's genesis. It's pleasant, for example, to see borne out his staunch belief in the appeal of non-rhyming, rhythmic lyrics such as those in show standouts like "Rock Island" or "Trouble", as well as his conviction that an old-fashioned, real barbershop quartet could have modern stage appeal.
For the majority of the short book, though, to appropriate from Gertrude Stein, there really isn't any there there. Wilson made over forty revisions to The Music Man before it ever played on Broadway, but he doesn't really give much of an idea how drastically (or not) the work changed over the course of those revisions. There's very little inside gossip or insight about the show's stars or production team. The Music Man is a considerable accomplishment, and Wilson is right to be proud of the hard work he put into it over the better part of a decade, but I can't really say I knew much more about it coming out of Wilson's book than I knew going in.
And now matter how "Iowa stubborn" Wilson fancies himself, or no matter how much a man of the folk, there's really no excuse for a copy editor not to have fixed the multiple occurrences of "should of" throughout the work.
