Of Monsters And Men will cameo in an upcoming episode of Game Of Thrones

They follow in the footsteps of ethereal compatriots Sigur Rós, Wilko Johnson, Snow Patrol's Gary Lightbody, most of Coldplay, and Mastodon.

A fan spotted Nanna Bryndís Hilmarsdóttir and Arnar Rósenkranz Hilmarsson on the set in Girona, Spain, in full medieval garb (albeit plus shades), near the Sant Pere de Gallivants monastery.

It's unknown when the episode they (presumably) feature in will air, or exactly what role they will take. Hopefully they fare better than poor George Dubya.
