Pretty thorough lists everyone!
I would add John LaTouche to the list of people you really must have in your library.
The Golden Apple (Shame on all of you for not mentioning this one before. Only one of the best sets of lyrics ever written for a Broadway show! Can you imagine what "Candide" would have been like if he hadn't died?) and the York Theater revue of his work "Taking a Chance on Love" (where you get some of his lyrics from "Candide" and rare goodies like songs from "The Vamp")
Then you should go on Ebay to get copies of those private pressings of shows that weren't recorded. But had soundsystem recording of the shows that have been bootlegged released. Shows like "Drat! The Cat!" and "Lolita, My Love"
I'm like WithoutATrace when it comes to collecting
"A coherent existance after so many years of muddle" - Desiree' Armfelt, A Little Night Music
"Life keeps happening everyday, Say Yes" - 70, Girls, 70
"Life is what you do while you're waiting to die" - Zorba
