There's a big black hole in a danger zone There's a rumbling ground down below There's a big dark town, it's a place I've flown There's a world going on underground They're alive, they're awake All the rest of the world is asleep Below the mineshaft roads it will all unfold There's a world going on underground Music All our roots hang down, swing from town to town They are marching around down under your boots All the trucks unload beyond the coffer holes There's a world going on underground Music
