Came across a clip at Open Culture (what a great website, by the way!) I'd heard of before, but never seen, of the very young Frank Zappa making his first ever appearance on tv playing the bicycle, on The Steve Allen Show back in 1963. Was struck by FZ's extraordinary presence and total sense of certainty, even as a clean-cut kid. Nice to see him genuinely smile a few times; the elder version seemed weighed down by the stupidities of the world in a way that often made smiles seem irrelevant - even when he was being very funny, as he usually was.
Not sure what he'd make of the America of today. Not too much, I'd guess.
