Here comes the version I know (sung by Mairead Taggart)

Working Man

Chorus
It's a working man I am,
And I've been down underground,
I swear to God if I ever see the Sun,
Or for any length of time,
I can hold it in my mind,
I never again will go down underground.

At the age of sixteen years,
He quarrelled with his peers,
Who vowed there'd never be another one,
In the dark recess of the mines,
Where you age before your time,
And the coal dust lies heavy on your lungs.

At the age of sixty four,
He will greet you at the door,
And he will gently take you by the arm,
Through the dark recess of the mine,
He will take you back in time,
And tell you all the hardships that were had.
