For history of the genesis of the show, you could start by looking at the press reports of the San Francisco tryout (which, by the way, needs to be described more. Who was in it? Was it the same director/choreographer?) Often authors talk about that sort of stuff in interviews early on. You might continue to find background about the genesis in interviews and press reports both before and after it opened on Broadway. As for the theatre scene, try John Kenrick's 2008 book or whatever very recent musical theatre books might mention the new trends, etc. For themes and analysis of book and music, again, a thorough examination of the the press reports and reviews should give some information; new musical theatre books might give some discussion; sometimes the vocal score sold at big sheet music stores might have a preface/introduction/afterword about it; likewise, if the script is sold anywhere, major libraries would have a copy, and there might be a good discussion in a preface/intro/afterword. Also liner notes to the recordings.... Season's Greetings! -- Ssilvers (talk) 03:36, 3 January 2010 (UTC)
