I am realizing that I have seen him in a number of shows, including Passione (a one-week flop in which he gave a very fine performance), Two Gentlemen from Verona, in which he had fairly small but noticeable role (probably more noticeable because he was so recognizable from all his years of performing with Anne Meara); Hurly-burly, again a not very large role, but another terrific performance; and The Ritz. I can still remember him screaming 'Get Proclo (sic)' in a boom that was probably heard blocks away. He was the definition of larger than life. In a very good way.
He was one of those people you thought was going to live forever, and he almost did.
