Wish I had some memorabilia to add to your records because I was there! I was in 7th grade when that concert happened and lived with very conservative Christian parents who barely let me out of the house for anything but church. But the year before, I'd sent Last Days Ministries' one of their pre-paid postcards requesting "So You Want to Go Back to Egypt" with the tiny check box near the bottom scratched off for people too broke to pay for it. I'd never heard of him and figured I was unlikely to get anything good for nothing, but a few weeks later the LP arrived in the mail. I played it so much in the living room that, by the time the concert in Peoria rolled around, my parents piled us all up in the Volkswagen bus and drove 2½ hours to hear him play. Even with the folks a few seats away constantly moaning and speaking in tongues, it was wonderful. I'm glad someone else remembers it.
