I had a blues sampler CD with a great song I can't seem to find anywhere. It had a fast but simple rhythm that was mainly 2 notes in a 4 beat. The chorus was 'Piece of mind you escape me, piece of mind you will break me.' The lyrics had a part like 'I only see my mother in December.' I've been searching Google and You Tube and have found a dozen songs called Piece of Mind, or Peace of Mind but they're too slow. It's not the Boston song, I'm guessing it was 60's or 70's.
