Last week the Institute for the Study of the Americas held a musical recital and commentary entitled "All You Jim Crow Fascists! Woody Guthrie's Freedom Songs". It was presented by Will Kaufman of the University of Central Lancashire. It was a very interesting evening - lot's about the life and the developing of Guthries beliefs - and some great music, illustrated with slides.
