You're off a we bit in your facts, but yes, you're in the right direction!
Folk music....It was HUGE in the 1930s-'40s and had a BIG following with teen. He collected and sang traditional, very old folk music. And I know all about him and this, because when Folk Music made a BIG comeback in the late '50s, I was a fan and my mother who had been a big fan if R D-B, told me all about him. :-)
There was a BIG Folk scene in Greenwich Village, prior to the likes of THE BROTHERS FOUR, etc. and Joan Bias, who began ONLY singing for real, OLD folk music from the UK.
It was THE BEATS ( also stinking COMMIE leftists and dopers), who began the decade plus later (1968) Hippie/dippy, crapola of late '60s!
So yes, INDEED, you did pinpoint the correct time line and progression...you just didn't add the NYC scene, which was HUGE!
My vague reference to the full fledged folk scene actually meant Greenwich Village.
You’ve got the Beats mixed up. The Beats go back to Jack Kerouac. I’m sure that you will recall that Neal Cassidy was Kerouac’s character Dean Moriarity in On The Road. Kerouac wrote about the Beat Generation. The same Neal Cassidy became the driver of Ken Kesey’s “Furthur” bus full of the Merry Pranksters (who appeared at Woodstock). That is why I said that Kesey/Cassidy are the link between the Beats and the hippies. Of course you know that the Beatles got their name from the Beats. I think they were playing in Germany as early as 1960. You just don’t get much earlier into the sixties than that! Funny footnote, the “Beats” were changed to “beatnik” to emphasis their Commie persuasions, ala Sputnik. No question the folkie faction in Greenwich Village were also “fellow travelers”.
