The song Lasairfhiona sings isn't in Abair Amhrán. And why would it be, if the words were only recently translated and set to music? (Abair Amhrán only contains lyrics in Irish Gaelic and was originally published in 1962, although it has been reprinted a number of times)Or if you are talking of an older song going to the tune of The Road to the Isles, do you know the title of it? I can't recall anything of that nature in in Abair Amhrán ... though I'm reminded of another song to a Scottish tune: Trasna na dtonnta, dul/gabhail siar, dul siar ...(Westering Home) and though I think that's in Abair Amhrán I can't find it now!
