Rambling Irishman chords by Oysterband

Here's an attempt at the Oysterband's arrangement of "Rambling
Irishman".  I believe the chords are right, but I may have the
tuning off.  They stay mostly with the bass strings and mostly use
downstrokes.  I have no idea what the language the chorus is in or
what it means - any help is appreciated.  Very cool song though.

Tuning low to high -  DADGBD

Chords  D  000230
        A  x02220
        G  5x0030
        Bm x24430

Long instrumental intro not done.
