Mná na hÉireann
IMHO, the most beautiful melody ever written...
There are lots of covers of this tune on Youtube, including several by Jeff. Its worthwhile hunting down a few of them. It also is the main theme of Kubrick's Barry Lyndon.
Damn. In spite of all its problems, I'm gonna miss this planet. Even all the wicked little monkeys that systematically ruined it. Having said that, they did leave some gems behind...
