I compared the text that Brakn posted with the lyrics that Daniel O'Donnell sings in the YouTube recording, and I made a few corrections. I also "wickified" the place names, in case you want to verify the spelling.
DESTINATION DONEGAL John McCauley As sung by Daniel O'Donnell
1. As I stand above the starboard bow and watch the ocean foam, As I view each new horizon I grow further from my home. I'm sailing on a foreign ship that's bound for Montreal, But I'll view the world and make my destination Donegal.
3. O Donegal, I miss you and I'll never understand Why I left you for these foreign lands against my heart's command. Whatever fortune comes my way, whatever may befall, I know I'll make my final destination Donegal.
