Mo ghille mear
Buachaill ón Éirne
tune for Buachaill ón Éirne

all on Mudcat

there's a recording of Buachaill on Éirne on a Liam Clancy solo album (late 1960s release I think)

your question is very broad indeed
there are some CD/songbook combinations available,for example Ó Baoill, Ceolta Gael

lots of recordings in Irish at http://www.cic.ie
