As a freshman at the U of Colorado in 1959 (yes, it's true), I was fortunate to have as my anthropology prof, Dr. John Greenway. On occasion he would bring his guitar to class and introduce what most of us had never heard before or new existed; such as, talking blues, Australian folk, etc. What seems now as a simple gesture had a very big effect on my views towards music. The timing was right- 2 or 3 years either way may not have had the impact. I know Dr. Greenway's still exist on Folkways- but is he still alive, etc.?
