"Red is the Rose" Irish nationalist? How did I miss that one? ;>)>

As for Loch Lomond: Many Scottish (and other) songs have had Irish language lyrics fitted to them in modern times, often in the context of helping to teach children Irish by using well known tunes. I think there is at least one such to the air of Loch Lomond - but it doesn't come to mind as of yet...
