I remember that song. I was a sophomore in high school. I didn’t really get it, except that I knew it had something to do with the peace movement and hippy culture. There were some kids in my class who were becoming hippies; some kids were getting into the drug culture.
We got a new, young physics teacher that year. He soon disappeared. Many years later I found out he was busted for pot. I think it was handled within the school; I don’t think he was arrested, or that it ever got to law enforcement. Which was good; at that time, NY was under the “Rockefeller drug laws,” and penalties for even possession of an ounce were draconian. For a high school teacher, busted on school property... well, he would have been in a world of hurt.
I was a Junior in High School when it came out. I loved it because I was into martial arts at that time.
I watch it again as an adult and thought it stunk on ice.
