As happens often, someone mentions something that triggers memories of how much I too was moved by the thing mentioned. Michael K. has just done that. I'll have to dig out my Doors albums and crank them up. And rent the movie again while I'm at it.
Virtually all music of that era seems shot through with images of war, regardless of the content of the song. Probably why Stanley Kubrick, in his Vietnam movie Full Metal Jacket, chose "Goin' To The Chapel" and quirky tunes like "The Bird Is The Word" for the soundtrack. That or cinematic irony.
My first introduction to the Mudcat was a request for information on Tom Paxton's "Talkin' Vietnam Potluck Blues."
Donovan's "Catch The Wind" stands out.
Psychedelic-ally speaking, "Somebody To Love" by Jefferson Airplane; Frank Zappa's Lumpy Gravy and Pink Floyd's Ummagumma.
All this is making me want to put on my tie-dye tee and American flag bells, turn on the lava lamps and blacklight posters, brew some tea, burn some incense, and sit crosslegged in the middle of the floor with my guitar and contemplate my belly button.
