I saw him at Caroline's in NYC eons ago. Let's just say he was on automatic -- but I guess that happens. Even though I suppose he was under 40.
You couldn't understand a word he said, even though we were fairly close to the stage.
Allegedly, he was apolitical. But I remember him at the 1992 Golden Globes (no, I wasn't there), Lewis devoting much of his routine to mocking Oliver Stone's nominated "JFK" movie (while Stone, at a table in the back, nervously pretended to be reading his menu).
I saw Lewis a few times in the '80s on LETTERMAN. Sometimes his ranting was kind of amusing.
He had great hair, however, for years and years.
