      Slavering for every last bit of Game of Thrones news to tide you over until this Sunday's season-seven finale? Well, so am I.

      Unbeknown to most of us, behind the fierce facades of Ser Sandor Clegane (also known as the Hound) and Tormund Giantsbane there lurked two songbirds just waiting to get out.

      On the show, the characters (played by Rory McCann and Kristofer Hivju) display a rather fractious working relationship. But in the behind-the-scenes video below, it's nothing but sweet harmony as the two try to sing "Yellow Bird", previously covered by the Mills Brothers and Chris Isaak.

      This just might be my new favourite song.
