Looking for one thing on YouTube, you always find another. I have posted other close harmony groups in the past, Orpheus, The Kingston Trio - but always chuckling at them a bit. Chuckling at myself, perhaps. Yes, these two similar videos have guys with funny clothes and haircuts, but it goes with the territory. They were in the crossover period from fresh-faced folksingers to hippie exuberance. And I loved them. Still do. Without a trace of irony, this is good music.
Also, I looked a lot like that rhythm guitarist, so I'm a little defensive.
