 We were backing up a few of the artists. We backed up John Lee Hunter for a set. That went great. Then we were going to back up Big Mama Thornton for a set. So we played one song, and she threw the whole band off stage except for me. Really, the only thing on stage was a big old upright piano in those days. So she went behind the drum set, played drums. She sang and played harmonica. It only had one harmonica, and I believe it was like an F-sharp.
