Michaelr, I've listened to the song and it does sound a bit like Scots Gaelic but I suppose that could be due to the accent or dialect. I'm from Co Waterford in the south-east of Ireland and the Co Donegal people [Tír Chonaill] do sound a lot like the people of the Western Isles to me. From what I can understand it is one of those "Celtic" New Age or soul lyrics that consist of little phrases and expressions of longing rather than a story. But I wouldn't accept the translation you were given. The chorus seems to just say: 'You could, you could stay, you could, you could go, you could see the life that's before you, you could, you could.' The first verse seems to start with: 'Walk through the meadows, down to Rann na Mart[?], and you'll see.... [here it probably names all the beauty spots along the coast but that's only a guess]. The second verse seems to say:'You could go out over the border[ another guess], stay here, listen to the quiet sea, listen to me.'

It might be as someone said earlier, a plea for young Gaeltacht people to come back home. That would make sense as all the Gaeltacht areas suffer from the loss of the young people who are the life blood of a district and its future.
