I got a book today from amazon - called Hard Times: The Adult Musical in the 1970s. Even though it mostly concerns itself with live adult musicals like Oh Calcutta, the lady author, who I apparently corresponded with in 2007, devotes a rather large amount of pages to Nudie Musical - all very interesting. She gets a couple of facts wrong, but she's got some really interesting insights from her perspective, and she obviously adores the movie. Very nice.
