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 mineshaft 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
