Between the ages of 13 and 20, yer usually date-less blogger spent many a Saturday night with an impassive middle-aged man sporting plastered hair, leisure suits, gold chains and the occasional sweater vest. His name was Don Kirshner, and he brought the top rock acts of the day into my living room with his syndicated late-night TV show. For many of us growing up in the 1970s, pre-car and pre-cash, the closest we came to attending an actual rock concert was staying up late to hear this pathologically unhip music impresario kick off 90 minutes of authentic live-on-tape rock performances.
