Sixteen Tons.... no kidding

Some people say a man is made outta mud.
A poor man's made outta muscle and blood.
Muscle and blood, skin and bones;
A mind that's weak and a back that's strong.

You load sixteen tons an' what do you get?
Another day older and deeper in debt.
St Peter don't you call me I cause can't go:
I owe my soul to the company store.

Well, if you see me comin', better step aside.
A lotta men didn't; a lotta men died.
One fist of iron, the other of steel.
If the right one don't get you, then the left one will.

You load sixteen tons an' what do you get?
Another day older and deeper in debt.
St Peter don't you call me I cause can't go:
I owe my soul to the company store.
