I think Mary McLaughlin's version of the Children of Lir is one of the nicest I've ever heard..sad and very much a lament.

It has a chorus that goes: I am Finnoula, the Daughter of Lir
                            Condemned to die for 900 years
                            These are my brothers; all three are here
                            A plaintive song falls on helpless ears

Can't remember the name of the album she recorded it on as a solo. I heard it when she was travelling with Anne Lister as Anonyma.
I still get a chill thinking about that legend, one of my very favorite Irish stories.
