"Bog Braon Don Seanduine" is the only song that I ever learned directly from a native speaker, so I am a self-proclaimed expert when it comes to this particular song.
Here are the lyrics:
Bog braon, bog braon, bog braon don seanduine,
Bog braon, is blais féin, is é a thabhairt don seanduine.
Cuir a chodhladh, cuir a chodhladh, cuir a chodhladh an seanduine,
Cuir a chodhladh, is nigh a chosa , bog braon don seanduine.
Ubh circe, ubh circe, ubh circe don seanduine,
Ubh circe, is blúirín ime, is é a thabhairt don seanduine.
Cuir a chodhladh, cuir a chodhladh, cuir a chodhladh an seanduine,
Cuir a chodhladh, is nigh a chosa , bog braon don seanduine.
Feoil úr, feol úr, feol úr don seanduine,
Feoil úr, is braon súip, is é a thabhairt don seanduine.
Cuir a chodhladh, cuir a chodhladh, cuir a chodhladh an seanduine,
Cuir a chodhladh, is nigh a chosa , bog braon don seanduine.
Bog braon, bog braon, bog braon don seanduine,
Bog braon, is blais féin, is é a thabhairt don seanduine.
This is a really great song for learners of Irish, especially beginners, for several reasons:
1. The entire song is in the present tense, so a learner who only knows the present and imperative, can easily get through the whole song.
2. It's a slow song, so it is easy to sing (and understand while you're singing it) at it's normal pace.
3. It repeats a lot, so it's very easy to memorize.
4. This version (by far the best version, in my opinion) is sung by Iarla Ó Lionáird who is a fluent native speaker from the Múscraí Gaeltacht, so you can trust his pronunciation and grammar, especially if you are learning Munster Irish.
5. It is readily available on YouTube
