Rattle big black bones

in the danger zone

there's a rumblin' groan

down below

there's a big dark town

it's a place I've found

there's a world going on

Underground

they're alive, they're awake

while the rest of the world is asleep

below the mine shaft roads

it will all unfold

there's 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

there's a world going on

Underground
