Was this the Hell's Angels concert?
This was only the 2nd or 3rd show I had attended. When I arrived at The Hall there were Angels & Motorcycles everywhere.The show was actually a fundraiser for the "widow" ; i.e old lady (sic) of an Angel that had recently been killed. The show was interrupted several times by fights. My memory is a bit hazy, but I don't think the show played for the full time. I believe they had to stop early because of the fighting.
