I'm older than most, younger than many. I was drafted to service and reported to Ft Knox on 8 May 1969. Hendrix played my hometown venue, fairgrounds "coliseum" (or as Zappa called it - a Barn) on 11 May '69. I was very disappointed. No worries, I'll see him when I get out. Of course he died in '70. When I got out I went to every concert I could. There were a slew of mini festivals touring in those days. You could pay 6 or $8 and see as many bands in one day-night. Foghat ELO Chuck Berry Richie Havens Its a Beautiful Day Eric Burdon Ike & Tina Rare Earth BB King Johnny Winter Edgar Winter etc etc. At one such festival early afternoon, outdoors, Louisville '73ish.. (ok I was in a celebratory mood)(and maybe napping) and I hear All Along the Watchtower coming from the stage. My first thought was Jimi recorded. In fact it was Mahogany Rush. I had never heard of them. So few videos made from those days.
one from 2001 - youtube says I can't embed it 'Voodoo Chile Montreal 2001' if it doesn't show up
