Cover art for The Legend of Finn MacCumhail lyrics by Dropkick Murphys

True, that is an odd coincidence Dropkick_Rover. Anyhow, This song is about Finn (Fionn, etc) Maccumhail (McCool, etc) and his troop of brigands. Anyhow, BAck to Rover's point, my name is also of celtic mythology (Didn't want to confuse the yanks by spelling it Dubhlachan) but Saint Patrick, on an unrelated note, is the most anti-Irish figure that the world has ever seen. He drove "The Snakes" from Ireland. As any historian 'ould tell you, "The Snakes" is just a metaphor, it really means those of Celtic religion, hence, the Celts, hence The Irish. He Drove the Irish from Ireland. Too bad I can't go back to then, I'd kill him, even if they executed me afterwards. Then maybe more people would practice my religion. The small solace in this is that the religion has never faded, at no point in history since its creation has it had no followers. The survivors who did not eventually convert to Catholicism taught it to their children and so, on. There are still some families today who practice this religion, in direct teaching from the ancients and there are many people who have converted to new age versions of it, Wicca, modern Druidism, etc, etc and one day the religion may be full again, but only if the lessons are taught on after the endless controversy and struggle of Celts who are outnumbered by Christians. Anyhow, that is the message that this song speaks.
