"Walk Right In, Sit Right Down" from 1962

It's 1962, and I hear this folk tune with a high female soprano and chunky 12-string guitar. And it's the second part that gets me: the rich deep resonation of the instrument's depth and vibration. It hooked me on 12-string tunes and instrumentalists and musicians who played it. 

Just "Walk Right In" and let your mind roll on--which was the forerunner in my mind for "Tune in, turn on, and drop out" a few years later. Oh well--just groove on that butch flat top crew cut, fellas, and remember: that's why we grew our hair long. Dedicated to my musical brother from FB, Mark Breedlove. Oh, and the studio version has a much nicer and longer guitar break. Those guys were having fun.
