Game of Thrones: The Musical

Have you guys seen this video? I saw it on Tumblr and I've been watching it on repeat ever since. It's a video Coldplay and the cast of GoT made for Red Nose Day basically turning Game of Thrones into a musical.

It's pretty funny and some of the songs are actually super catchy. I've been humming "Red Wedding" and "Rastafarian Targaryen" for two days straight now. I say they should totally make this a reality. What do you guys think?
