You are the Disco Generation, as far as I'm concerned! My sister and brother fit that. They're a bit too old for mine, but definitely too young and too different from the so-called Baby Boomers. To me we mite as well call them simply the Hippie Generation. Disco people are definitely NOT hippies! (Thank God!!!)
You're right! I just graduated high school when Saturday Night Fever hit the screens (1977). Can't forget Animal House and Star Wars! The 70's were fun.
I guess that fits me, the Disco Generation, LOL. But my teeth were first cut on the Beatles. We are the kids from "That 70's Show", though I've never seen it.
Although born in '62, while a late teen, I once wore a punk T-shirt I produced (e.g. an old torn up one, to which I added safty pins and spray painted "art") through a nearby shopping mall. One of the things spray painted on it was "Disco Sucks!" ;) LOL ...
