Super Sunday Concert. I think it was 18 hrs. Our seats were same level as stage and just too close. The Who reportedly raddled windows [5] miles away. ... I lost my hearing for 3 days. .... During John Mellancamp's 1st set, we were bouncing beach balls around. ... Minimumal security, in those days, so, lots of partying. .... ah, Freedom ... Decades before Denver went Woke.
