I have a recording by The Houghton Weavers, here are my 'heard' lyrics:

MANCHESTER MAGGIE

Dublin Boy Paddy was resting in fields close to the Liverpool track
Paddy reflected with tears in his eyes there would be no going back
Manchester Maggie was munching away; she was contented a lass
Master had pensioned them off in the fields; they had been put out to grass

The Chorus -
Paddy said "What's gonna happen to us, Maggie? gossip is rife in the street.
Workhorses all of our lives, Maggie, we have been worked off our feet
Will we be wanted again, Maggie? just give me one little sign
What's gonna happen to us, Maggie? what's at the end of the line?"

"Remember them carthorses down by the docks pulling their lumbering craft
They seemed contented and I said to you carthorses they must be daft
Remember when one of them said to his mate 'Look at them heads in the air'
Little do they know they'll be obsolete; Dobbin, let's offer a prayer

[Chorus]

Dublin Boy Paddy was resting in fields close to the Liverpool track
Paddy's poor legs were arthritic and bent; he had a pain in his back
Manchester Maggie was munching away; she was no longer a lass
Saint Peter had them out by Sugarloaf Hill in daisies and sweet meadow grass

[Chorus]
