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
