I have around 40 Zappa bootlegs (mostly on vinyl) and around 60 of his official releases (about half of those on vinyl) a few CD's and a few VHS tapes and DVD's, along with a couple of tour shirts from shows I saw and a couple of 60's Mothers of Invention concert posters. I've also seen The Grandmothers and The GrandMothers of Invention, and have some albums and CD's and a tour shirt from The Grandmothers. Over the past 15 years, I've also had the opportunity to chat with several members of the original Mothers of Invention as well as several members of Zappa's solo bands from the 70's & 80's.
Needless to say, I'm a fan.
