I just worked out the chords for Altan's version of "The Flower of Magherally."
If the line breaks work on this post, each line of chords will represent each line in the first verse. I think they do some different variations on other verses.

Dm        Am7        Bbmaj7        
Gm7        C9        G7/B
Dm   Am7        
GaddD        C9        Dm2 - Dm
F    C
Dm    Am7
Dm    Am
GaddD   Am   Bb   C
