Bill "The Brick" Jefferson (Drums) is the solid foundation of the band. Once, at one of my brother's gigs, their drummer hadn't shown. Bill was around so my brother asked him to sit in. For the first few numbers, my brother told Bill the song they were doing and asked him if he knew it. Bill kept saying "Yeah, I know it". After about the fourth number, Bill said, "Look, just assume I know everything".
