text: Rattle big black bones in the Danger zone
  Theres a rumblin groan down below
  Theres a big dark town, its a place Ive found
  Theres a world going on underground
  Theyre alive, theyre awake
  While the rest of the world is asleep
  Below the mine shaft roads, it will all unfold
  Theres a world going on underground
  All the roots hang down, swing from town to town
  They are marching around down under your boots
  All the trucks unload beyond the gopher holes
  Theres a world going on underground
