I am not sure what possessed Oak Park (IL) High to invite Mr. Sandburg to address us proto-rockers, but he came to the assembly and got up on the stage with his guitar and talked and sang for an hour. Some knew about him - nobody could have guessed the "great folk scare" was coming - one of those in attendance, besides me, was Erik Jacobsen, who went on to produce the Loving Spoonful records. That was the same year that the Old Town School of Folk Music started in Oak Park.
Maybe Mr. Sandburg had wider influence in what we do know than he is usually given.
