I was raised by my G Parents who must have been "hep" because they loved Elvis, the Beatles, Jerry Lee Lewis (my Grand Dad would mimic his piano playing) Little Richard, hell, all the '50s acts.
I remember that from Feb. on thru the rest of the summer it was nothing but Beatles, Beatles and more Beatles on the radio. Promotions, contests, all kind of shit. When we went back to school there was a whole lot of long haired boys.
If memory serves they were the #2 group in the U.K. behind the Animals. That chance meeting with Sullivan...what if the Animals got on American T.V. first?
