So you're a fan of the show?

"Yes! The author [George RR Martin] is my age and it blows my mind that he's able to create this vast, interlinked world. As a songwriter I write little movies. But I can't imagine sitting down and writing even one small book. But then probably somebody like him couldn't imagine writing Edge Of Seventeen or Rhiannon - couldn't write a whole little life in two verses and a chorus. And of course I would love to write some music for Game Of Thrones. I've written a bunch of poetry about it - one for each of the characters. On Jon Snow… On Arya… On Cersei and Jaime."

Sounds like someone hasn't heard The Rains of Castamere.
