the musical performance especially jimi hendrix make this a keeper . but the other material be of decidedly variable value . wavy gravy work for a while and then becomes tedious a hell and most of the concert goer aren not terribly interest . i do hope the one young lady who lose her sister in the crowd be successful in find her and though . the thought that run through my mind watch this during crowd scene and interview be and how many of these people be grandparent and ceo of corporation and drive bmws and the like . after all and it have be 31 year since woodstock . they have become the generation they be warn not to trust . oh and well . good luck next time .
