Allegro - Published Libretto?

I recently stumbled upon the 2009 studio recording of Rodgers & Hammerstein's Allegro. While it's billed as complete, I was curious about the book and any character descriptions, stage directions, etc. However, the libretto seems to be extraordinarily difficult to find. I checked the Drama Book Shop, Amazon, did a good-old fashioned Google search. Anybody know where I might track it down? I'm just beginning to learn about this little gem and never having seen it I'd like to understand more.

The libretto is published in a collection of R&H librettos. It includes 6 of their musicals, including Allegro. I believe the book is called "Six plays by Rodgers and Hammerstein" or something like that. See if you can find it on Amazon

EDIT: posted this at the same time as Peter :)

Every musical theater fan should own '"SIX PLAYS BY RODGERS AND HAMMERSTEIN".

Even though your primary interest is ALLEGRO, you'll be glad to have the others.
