 But the new version is much slower and more melancholy, almost as if it were being sung in a church, with Prior being backed up by Knight playing an organ.Perhaps the biggest change is on "When I Was On Horseback".The original version, off "Ten Man Mop, or Mr. Reservoir Butler Rides Again", is a slow, sorrowful funeral tune, but the new version is a mid-tempo rock piece, with a driving violin, a brisk guitar line, and a strong drum beat.
