Recognize these performers? Probably not. They're the group "Square Root" and like most of the performers you'll see in this post, they weren't exactly headlining at Shea Stadium..... in fact, they were lucky to headline at the Holiday Inn. But then, that's not necessarily an insult - all bands have to start this way. The Beatles payed their dues at the Cavern Club, and Square Root probably played their asses off at plenty of local dives.
I can't help but wonder what ever became of Square Root and these other acts that, for whatever reason, never made it big..... if you happen to know information on them, please drop it in a comment.
