If anyone is in doubt about the correct text of ON RAGLAN ROAD as intended by Patrick Kavanagh, it might help to consult several print copies that are available through Google Book Search:

Very Best Irish Songs & Ballads By Pat Conway, 1999, page 11.

Irish Writing in the Twentieth Century: A Reader By David Pierce, 2000, page 780.

Gather Round Me: The Best of Irish Popular Poetry By Christopher Cahill, 2004, page 45.

These books are still under copyright--so is the original poem, apparently--and so the complete books are not viewable. They are in the "limited preview" category. Only selected pages are viewable, and those pages happen to include ON RAGLAN ROAD. (At least they are viewable to me, in the US, but we have found that some books are not viewable everywhere.) I suppose the publishers have given permission for excerpts to be shown, in order to promote sales of the books. (I wonder how that works, when the publisher of an anthology is not the owner of the copyrights on the original works?)

Anyway, I find no significant discrepancy between the Pierce book and the Cahill book, but right off the bat, I see that the Conway book has "I saw her" where the other two have "I met her." Also Conway calls it RAGLAN ROAD where the other two call it ON RAGLAN ROAD.

I'm inclined to believe Pierce and Cahill rather than Conway.

I'm speculating here: Maybe the editors of "poetry" books are more careful than the editors of "song" books. Maybe people feel that calling something a "song" rather than a "poem" gives permission for the folk process to creep in--even when the text is credited to a known author.

Conway does have the music "lead sheet" for the first verse, as well as chords.
