Game of Thrones the show opening sung by Sansa, Arya and Bran

All the Game of Thrones season 1 blu-ray and dvd commentary tracks are awesome, but this bit from the start of episode 3 made me smile, just had to share it.

*update*
Season 2 commentary tracks are equally awesome www.youtube.com/watch?v=jnKxlncdZoM
