MacColl re-wrote it along with a bundle of under-sung songs for the film, 'The Irishmen' - the film was never shown because the BBC got cold feet
Peggy gave me a file of all the songs if anybody would like them
Other rewrites include
Deveil and Ganger McGlinn,
Indeed I do
Rambler from Clare
Van Dieman's Land
Rocks of Bawn   and others
One of the only songs to become generally poopular was 'Tunnel Tigers, thanks to The Johnsons

FAREWELL TO IRELAND (1966)

Farewell to the groves of Shillelagh and Shamrock,
Farewell to the girls of old Ireland all round.
May their hearts be as merry as ever I would wish them,
When I'm away from my own native land.

My mother is old and my father defeated,
By hard work and poverty; it grieves my heart sore
To see them so patient with all hope departed,
And now I must leave them for a foreign shore.

Then farewell to the green hills and lakes of Killarney,
Farewell to the white strand where green billows roll;
Farewell to Blackwater and to wild Connemara,
The pinched face of charity and life on the dole.

The pastures are fenced and the woods are protected,
The pheasant and partridge they nest in the field;
While away 'cross the ocean go journeymen tailors,
And fiddlers who flaked out the old mountain reels.

Young boys and old men and the fathers of children,
In search of employment from Ireland must go;
Abandoned, disinherited, the landless of Ireland,
From Kerry, Cork and Leitrim and the County Mayo.

Then it's pack up your bag and consider no longer,
The boat's at the quay, so it's shoulder your load;
Turn the key in the door, take a last look at Ireland,
The land's for the bullock and the men for the road.

Re-written from a song of the same name recorded from Paddy Tunney of Beleek, Co. Fermanagh and used in a film called ‘The Irishmen’, about building labourers from Ireland working in Britain.
