My older brother and I were visiting relatives over Christmas and I got to tag along with him to this show. I was 13 at the time and this was my first rock concert. As I recall, it started about noon and ended with AB closing the show about 2:30 am. By sundown, it was freezing and I remember the cops having a cow because there were several “campfires” being lit. Wet Willie and John Hammond also performed. John McLaughlin was amazing and Edgar/Johnny had everyone rocking. Truly an awesome first concert – became hooked on blues and fusion everafter.
