"We're looking for songs that are (possibly) traditional, older, not as well known, more stand alone type stuff."

That's what M originally asked for.  Nearly everybody who has since replied has made well-meant assumptions about what she was asking for, without actually paying much attention to her question; mostly they have suggested songs which are over-familiar from popular recordings by Irish performers, a good few of which are either English or Scottish songs (borrowed and sometimes not acknowledged) or American "fake Irish" commercial products.  Antóin made that point, and got an immediate, and entirely unjustified, put-down from Edel.  Áine's suggestions are, as ever, intelligent and well-informed, though obviously I'd disagree with the apparant suggestion that songs in the English language are not really Irish songs unless translated from Gaelic originals, as would a good many respected Irish traditional singers.  To Áine's recommendations I might just tentatively add, as possibilities among many others, Ned of the Hill, The Green Fields of America and As I Roved Out; all easily found on the DT, and, while relatively well-known, nevertheless of a shape which would permit interesting interpretation in the format M describes.
