No Alice, I don't know this song, not by the title anyway. And JohnT beat me to telling you that "lúibín" is a generic name for light songs. Sometime Mudcatter Antaine has sung at lúibíní competitions at the annual "Oireachtas" Irish language festival, as well as singing in the sean-nós competitions. Maybe he could help. I'll look out for the relevant Mary O'Hara album
