I am fascinated by the places that music comes from, like fife-and-drum blues from southern Mississippi or Cajun music out of Lafayette, Louisiana, shape-note singing, old harp singing from the mountains - I love that stuff.

I can remember when President Nixon basically said, 'All troops have been withdrawn from the delta.' And I said, 'Wait, I'm still here.
