This is awesome for two reasons. One: Will Champion is a great name for a GoT character. What house wouldn’t want to be named Champion? House Champion, We Always Win. Even the Lannisters would be afraid of the Champions!
And two: Maybe this means “The Rains of Castamere” will be included on Coldplay’s next album! Just don’t play it at a wedding.
The video can be seen below (Champion’s the guy with the beard and hat rocking out on the drum).
