This isn't new territory for the show as another indie band, 'The National' performed the somber "The Rains of Castemere" during season 2. Pretty cool for the showrunners to do stuff like this, although I'm sure there was no shortage of talent willing to participate. But it really lends depth and character to the world created for the show. I love the touches like this, especially for "The Rains of Castemere" which plays a big role in such a pivotal scene in the books.
Lyrics to "The Bear and the Maiden Fair":
So get hyped, because season 3 starts March 31st at 9pm EST on HBO. Which means more of the enchanting Rose Leslie as Ygritte.
