I know some fans of the show already did a deserved homage to him and his characters, but it's never enough to praize someone's talent. he really was good! and I truly believe that his very unique voice will be remembered, together with his performances for many many years to come.
I know a "thank you" seems too little to give back to an actor as great as he was, but unfortunately it's the little I can give, as well as assure that his acting skills and performances will be remembered for as long as I remember them. my deepest condolences to his family and to his colleagues and, once again.. thank you John Spencer
