So what is the earliest concert you can remember going to

Paul McCartney and Wings Concert in Sept 1976 In Vience Italy at St. Marks Square.....
Oh man that is righteous! Me and a buddy bought a round of cheese and some narly bread and a couple of bottles of wine then listened to the music from the four corners of the square and decided we could sleep when we were dead. Stayed up all night and watched the sun rise munching bread sipping wine in St Marks square. One of my best memories of all time. Did you know gondolas are hard to drive if you happen to appropriate one? Just sayin......
