Sam Cooke: 'Wind' Led to 'Change'

I've posted previously that Sam Cooke, greatest male singer of our era, going back to his gospel days, was inspired to write "Change Gonna Come" (our greatest song) after he heard and recorded Dylan's "Blowin' in the Wind"--believing that a black man should--must--write such a song.  So he went out and topped it, just before he died. But I didn't know there existed a tape of Sam doing Dylan live, on Shindig, in his final months.
