I might add, since I wrote the above post, I knew the Kweskin band well since I had gone to Kweskin rehearsals and gigs, as well as those of the Even Dozen Jug Band, which my brother was in. Therw was a lot of cross-pollination between the bands, the most obvious, of course, being Maria D'amato (Muldaur) having joined the Kweskin band after her participation in the Even Dozen. I was in roughly 7th grade at the time and sometimes had to sneak into gigs or cut classes. David struck me as a very charismatic, mysterious guy. He played a character in many of his vocals, and I had the sense he was living that life. As Steven Stills sang, " To sing the blues you have go to live them, too." From what I could see as a teen, he was living them, to the point of self-injury. Nonetheless, he was always so kind to me and made me feel welcome despite our distance in age.
It's weird how many folk aficionados awant to talk about David Simon. He is a subject that intrigues many of us who lived so much to those records, and cuts like " Ukulele Lady." You couldn't help wonder about someone who got so into character in those vocals.
Years ago I had the delight of discovering that Vince Martin was still alive ( of Martin & Neil.) He has since left us, but I had a delightful reunion with him, even made a documentary on him. I had hoped maybe to discover that Simon, chameleon that he was, had simply transmogrified into some new character and was with us still. Alas, not, but we have those magical vocals...
