I can't agree with you, Moira. You are right that your version of this line is the usual one, but in the Bothy Band version Triona sings definitely something else. The line before says something like that every step she is taking (up to the gallows) and then I hear
"was a swifter than the furl wind" (pron.:"whined")
I wouldn't bet on this version (I have difficulties making a sense of it), but the "rode swifter than.." line gives a worse fit to what she sings.
Bill, I have no idea for the other line: "kiss me" makes more sense but she doesn't sing that, and "miss he" (what I hear) makes less sense than your version.
