Transcribed from your video. Had a bit of trouble with one word towards the end.

It's a hell of an age, puts a man ill-at-ease
Sets his mind in a rage, makes him weak at the knees
When he sees things are changing and he's marking time
His work-mates all twenty, and he's past his prime
And he longs to go back home to Ireland
I've heard he's tired of the crack and the living is rough
And his twenty one years on the buildings have taught him
When you have got nothing then you've had enough

So he sits in the bar and he smokes his cigar
And he boasts how he's never alone
Ah, but I know he's lying, his big heart is breaking
Murphy can never go home

And he reads in the paper of the economic miracles
Brought by the Yanks and the men from Japan
Building the blocks of the 21st Century
What use have they for a laboring man
Once hard men were heroes but now they are fools
And all the old values, uprooted and gone
And when he woke up he found they had changed all the rules
Well, there's nothing to do but keep laboring on

So he sits in the bar and he smokes his cigar
And he boasts how he's never alone
Ah, but I know he's lying, his big heart is breaking
Murphy can never go home

And it's a hard, rocky road that first took him to Birmingham
Long in the making with no going back
He was writing no letters, nor words of his whereabouts
No family at all for to help him keep track
He can stay here all night in no hurry at all
Cause there's nobody waiting but old Father Time
And as the last rays of sun, they go down on the Brohm????
A song from his childhood he quietly will rhyme

As he sits in the bar and he smokes his cigar
And he boasts how he's never alone
Ah, but I know he's lying, his big heart is breaking
Murphy can never go home
