Andy Ruck is a singer/songwriter from Northern Ireland. He doesn't nail himself down to any one genre, but you're not likely to see him writing for AC/DC, I don't think.
We've had a lot of songs about ghosts this year, but Andy may be the first one to name his. "Mary Cunningham (The Christmas Ghost)" is a story song (as Harry Chapin liked to call them), so you have to pay attention to the lyrics. And the song has that kind of Soul only Irish Folk has.
