Darach O Cathain does a good version of this song, but his is kind of different from the Clancy Brother's version (the more well known one)- when Darach last sings the chorus the second line is different.

Darach's Irish but maybe it's that version that's in Scots Gaelic? I don't know either Scots or Irish Gaelic, so I wouldn't know, but I've never really heard any difference in between several different versions of the song, except for Darach's. I myself could never find lyrics for his version, might anybody have lyrics?
