In between songs of Beatles/Stones/Dave Clark/Who etc., which I loved, someone put this one on and I was like struck by lightning at the age of 13.
Haven’t ever met anyone who loved this one too, do you?
For me, it was this Donovan tune:
likewise. First time I’m ever heard this song and the one Nick linked. I guess I’m a Donovan ignoramus 
Yeah, I was a fanatic back then. Learned Sunny Goodge Street and half the songs from “Gift From a Flower to a Garden”. Saw Dononvan on the Rock and Roll hall of fame and he was awesome, his speech was a lyrical poem, never gave an inch…
Donovan has been productive far beyond his 60’s heyday and some of the stuff is, IMO, quite good
When I heard it when I was about your age ( 
)I thought it was very close to Dylan’s “Chimes Of Freedom”.
The first song I recall in the way you suggest was The Cascades’ The Rhythm Of The Rain (or some such).
