It really wasn't a concert as they played there all summer. 1963 at the Miramar Ballroom in Boise, ID - Paul Revere and the Raiders. They were sure young then, just getting started but they had that sound. I was at Mountain Home AFB and yes I also remember where I was when Kennedy got shot. All leaves/passes denied and we went on alert USAF-SAC. Then Coasters at Anderson AFB, Guam 1964 between sorties(?).
