Yes it would be nice to get more information about the first wave of coffee houses and poetry readings that hit here after the San Francisco Renaissance of Allen Ginsberg & Ferlinghetti mid 50's.
It came to me---David Hale was the owner of the Purple Turk Coffee house on Central; for more info on Greenfield and the Tom Davies bookstore/coffee house maybe contact Eric Patterson who now has the Tom Davies Bookstore(if it is still there)on Central near Nob HIll.
---------------What about Old Town? That was a kind of bohemian hangout in those days. There may have been other poetry readings there.
Two other memories: Downtown Saturday Night series 1978 or so (Bill Bingham and Keith Wilson were on the same docket one night) and a place next to Univ. Drugs Store called "the Ugly Club" ---most folk singers but some poetry reading (opened and closed from 1995-66). It is Pericos Tacos now. Everett Campbell
