I have always felt that if you love to play your instrument and you sing songs you love,you will be very entertaining. In the sixties,it was very necessary to give a brief explanation of a song;we all had to learn from one another. This was not really an academic study;there were some great performances in the basket houses in the Village. If you ran into a performer backstage or in a bar,you could stop to discuss a song or technique.We learned from one another.
