You don't usually see much singing and dancing in Game of Thrones.

That's largely due to the fact that anyone with a pulse is almost immediately killed off in brutal fashion, therefore ruining the chance of a spontaneous rendition of Shiny Happy People. Thank god for US Red Nose Day, however, which has seen cast members swap their sword-swinging to murder the art of music instead. Recorded with Coldplay's Chris Martin and Liam Neeson, it looks like a lot of fun in aid of a brilliant cause. Oh, and you can donate here.
