I own some of his music, mostly on cassette. I have VCR tapes and DVDs of his performances, including Hated. I have archival interviews on both formats as well. I think I still have copies of Maximum RocknRoll with letters/essays he wrote (Flipside too, if I remember correctly).
I never did get to see him live. (I have seen The Meatmen and Mentors (before El Duce died) tho, so I got that goin’ for me!)
