I graduated from high school in 1975. Never heard of these guys.

Back then, FM radio was more of a regional thing. That song got a lot of airplay on Boston radio - WBCN if I recall.

I did not hear about ZZ Top until the early 1980s but they got a lot of FM airplay in the Deep South during the 1970s.
