I'm not familiar with the song and its difficult to translate from what looks like an innaccurate text.

Tiocfadh leat fanacht would translate more as Would you stay? Would you come is a literal translation. The last line of that verse would be I would come with you - a bit of a play on words here in that the phrase Thiocfadh leat can have both meanings.

Manus is from County Kildare with Donegal roots but has lived in Scotland for many years. I'd be fairly sure this is Irish rather than Scottish although he may have picked up some Scottish inflections during his time there.

If you can find an official set of lyrics I could have a go at translating it, although my gaelic is far from perfect. THe play on words in the first verse would be lost in translation.
