There was a huge live outdoor show in WVA about that year headlining Humble Pie. I missed it but I knew a lot of people who went. Big show with a lot of big names. I think it was a two day show. Everyone said the "Pie" stole the show.
I was a senior in HS at the time. They played with a band called Sweat Hog. I'll never forget it. It was the third big concert I went to. My first was Zeppelin at the LA Forum.
