I was 17, in the lower sixth. I have no idea how it came together,but I went to Lincoln with Wendy and Joy, friends from school in Wendy's dad's Austin. I recall driving it into the field where we parked and almost getting stuck. I think I remember the tree, but really only two things stick out in my memory: Meeting James Taylor who was a hero of mine at the time, talking for a little while, then asking for his autograph, knowing how crass it sounded, and he said 'you know what a pile of crap this is'. Didn't I know it! The other is of the Byrds (more heroes) crashing into 'So you want to be a rock and roll star' under the lights. I was a bit of a folkie, but at that point I knew where I was going next. I wish I could say great memories, but they're really only mental snapshots - scenarios, after 40 odd years
