I picked up my shovel and I walked to the mine
I loaded sixteen tons of number nine coal
And the straw boss said "Well, a-bless my soul"
You load sixteen tons, what do you get
Another day older and deeper in debt
Saint Peter don't you call me 'cause I can't go
I owe my soul to the company store
From his song "16 Tons"; country and western singer Merle Travis was the son of a coal miner.
