Dark as a dungeon

Well c'mon all you fellas
So young and so fine
Seek not your fortunes
In the dark dreary mine

It'll form as a habit
And will seep in your soul
'Till a stream of your blood runs
As black as the coal

Where it's dark as a dungeon
And it's damp as a tomb
Dangers are double
And the pleasures are few

Where the rain never falls
And the sun never shines
Its dark as a dungeon
Way down in the mine
