ZZ Part I

Be there or be square.

According to that infallible source Wikipedia, ZZ Top created its signature sound during its first decade, 1973-1982. Let's use 1978 as our half-way mark thorough that decade and do a little arithmetic.

In 1978 I was a 20 year old undergraduate. 

2014 - 1978 = 36

1978 - 36 = 1942

Somewhere I have a crappy old book (or maybe two) listing top ten songs, popular bands and singers, and so on from years gone by. I'll see if I'm able to find out who was marching in the hit parade in 1942.
