So what is the earliest concert you can remember going to

Keep in mind most on this thread are of an age when glass was banned from concerts so everybody took the bag with a cork! Leafy like material just got passed down the rows if you were in the seats. How are any of us possibly supposed to remember details like year and location? I remember my Harley being unceremoniously tossed in back of pickup more than once by folks not understanding carburetor side up! Then crawling in on top of it for ride home! Holy smokes what a great thread!
