When it comes to a troop of Roose Bolton's men trotting through a forest, it really doesn't matter who the actors are riding the horses. However, Benioff and Weiss both decided to bring in Snow Patrol frontman Gary Lightbody, the man credited with writing their biggest hit, Chasing Cars. He starts the group off singing The Bear And The Maiden Fair, during Season 3 Episode 3, though the song's namesake episode didn't come until later in the season, without Lightbody featuring again.
