My first show was the Darkness tour (I was 15) and thats always been my favorite also. My older brother by 4 years was at the New Years eve show in 1975 at the Tower Theater which you may be familiar with as it is one of the top bootlegged concert tapes out there.
One sentimental thing about this show will be that I was at the the Opening Night for The River tour. It was at Chrysler Arena at the U of Mich where my brother did his undergrad. My whole family was visiting him and we all went including my parents. We had my mother sneak a nice camera with telephoto lenses in her purse. I was walking behind the stage and caught Bruce mid air leaping off the piano which he stopped doing many years ago. I blew it up to 4'X 4" and it was on the wall of my bedroom the rest of high school, all through college and a bit beyond. It got damaged but I still have the negative.
