Worst without doubt was Marshell Tucker, about half the audience walked out and I wanted to.
Steve Miller gave us all a lecture on how gawdawful logging was complete with a slide show, I won't listen to him since.
Moody Blues need to practice or hire a guitar player that can play what was recorded, they sucked.

Leon Russell came out sat at the piano and played for at least two hours, he stopped once long enough to toss some tambourines into the audience. Great show
Seen a lot of performers most were good too excellent but those mentioned were all standouts..
