Shame on all you Folk Rock Brits for failing to so much as offer a breath of honorable mention to "The Incredible String Band" and how could y'all forget to mention "Donovan".
Now yer gettin' sloppy , now ,and yer gonna knock in off , right-right? ;-)
Favorite "synth-accompanied" Folk Rock piece has to be Greg Lake's classic folkish piece which was the 1st single Emerson, lake & Palmer ever published ; "Lucky Man" though Jon Anderson of "Yes" has always maintained a ready arm's-length reach to accoustic Folk replacing the "rock" with "spacey electrified accoustic guitar & harp ".
Favorite example " Wonderous Stories" which I was infinitely pleased to see performed "live" during their "Symphonic Tour"
at Wolf Trap in the Summer of 2001 and what a difference that back-up symphony orchestra makes.;-)
