There was a thriving coal industry in Arigna,, on the Roscommon/Leitrim border until closure in 1990.
There was plenty of traditional music (and still is) in the area- the great flute player John McKenna worked at Arigna before leaving for New York.
However, I can find no songs at all from any Irish coalfield (I think there was another one in Kilkenny?) There are plenty of Irish-American songs about the Molly Maguires etc and also UK songs of Irish origin- eg 'Johnny Seddon', from Durham, where many Irish worked in that coalfield.
The John McKenna festival hope to present an event at this year's commemorative festival about McKenna and the Arigna mines, so any pointers to such songs would be much appreciated!
