MartinRyan, the lyrics to "Bantry Girl's Lament" are in the DT. I have not seen the book in which the poem was originally published, but I believe that they are version (2). As sung by the Clancy Brothers in "Tales & Tunes," 1988, version (1). Not attributed to Kavanagh, but they are his. I don't have the cd handy, but I believe the Clancys did.
Also attributed properly at the guitar tab site I linked above (tabs arranged by Martin Simpson). These chords are for the simplified tune as performed by the Clancy Brothers and Van Morrison, and others.
