Alas, I'm too technologically challenged to listen to sound clips: I have ntl cable tv internet access and it doesn't do that sort of thing.
   My own memory (imperfect, possibly, and based on what Isla Cameron told me in the 60's) is that Isla got it, I think, from a Peter Kennedy related source. And sang it round the clubs, and I think recorded it, and that most of the subsequent version, including Clanceys etc, came from her interpretation.
Whatever the origins of the song, the "Irish Girl" line does suggest at least an influence from a British version of the song. Just as the tune "The Irish Washerwoman" was so-called in England: in Ireland it was commonly known as "The Washerwoman".   
However, the general flow of the lyrics, and the tune, sound totally Irish to me.
