I have an album called The Molly Maguires by a band called The Irish Balladeers. All the songs are those sung by the Irish in the coal mining area of Pennsylvania. It was on Avoca Records, released in 1968. I don't know if you can still get it.

The song about the Mollys in Ireland and their anti-landlordism fight is supposedly based on the murder of a Justice of the Peace in County Cavan c1845.
