I’ve been crawling all over the Web in an effort to keep my mind from becoming a victim of atrophy. In my travels I happened across this video. From a concert in 1972 at the Arie Crown Theater in Chicago. Note the audio is a little fuzzy and the video a bit grainy, but the performance is solid.
I am inclined to think that the message is as relevant today as it was then. Probably more so. Any takers?
