By the early 1960’s there wasn’t a teenager whose life didn’t revolve around music and his or her favourite radio stations and disc jockeys. A lot of the music irritated your parents, the DJ’s were full of energy and yelled everything, and the local commercials extolled the wonders of teen dances, drive in restaurants, acne cream, and (in California at least) the local Sunday Drag Races. We were all about music, dating, cars, and being cool, at least cool for whatever teen sub culture we wanted to be a part of. The music defined us, the trappings proclaimed us, and the accoutrements expressed our status. We were as conformist and as deeply shallow as every teen culture has been since the beginning of youth culture…lookin’ lame and proud as hell about it.
