In my experience most people who aren't Scottish or Irish can't really tell the difference between the music of Ireland or Scotland and it's very understandable I have a Clare friend who very nearly came to blows with me over my assertation that Peggy Gordon was a Scottish song.The late great Seumas Ennis once learnt a tune from a Barra man about the children of Lir who were changed into swans for 900 years by Eva his second wife,several years later a group of Irish musicians were at the feis in Barra and one of them a piper played the tune,an old man said that it was a Barra tune but the Irishman refuted this and said he had learnt it from Seumas Ennis the old man then told that it was he himself that had taught the tune to Ennis by singing it to him.The story of the children of Lir is obviously Irish in origin but then again the Scots originally came from Antrim so was the tune brought to Scotland or did it originate there because of the shared tradition.The Irish are so good at marketing themselves that it is easy for foreign songs to be thought of as Irish they are famed for their musicality and deservedly so,often the Irish flavours added to a tune are so powerful they can obscure the origins of the music entirely.They may steal the silver but they always give it back polished.
