Seems like only yesterday I was second posting on this thread, hell, it was only yesterday! This one surely started something.
Thinking on it, I suppose if I go back to schooldays, I had a music teacher who did a lot to open my ears. On our Founders Day at the service at our local church he played something on the organ which I had never heard before, but which haunted me for weeks. I still didn't know what it was so it was referred to as 'Andy's tune'.
Later I heard Pete Seeger play it on the banjo-- Jesu, Joy of man's desiring.
