The Kellies are some sort of Irish-y folk band who got famous more or less by accident. When I was little - around 10-12 - they were huge in Germany. I always thought they were a little silly, but everybody was listening to them, and it helped that I didn't understand the lyrics xD.

John Simm is awesome. He always plays these utterly insane and awesome characters, and he does it so well. I really want him back on DW. :D
