Remember how much you liked it when Pippin sang in Return of the King? That can’t even compare to how much Peter Jackson liked it. First the director used ROTK’s “Edge of Night†in the teaser trailer for The Hobbit: The Battle of the Five Armies, and now he’s brought back actor Billy Boyd to sing a new song, “The Last Goodbye,†over the end credits of the final Hobbit movie. Boyd apparently wrote the song alongside Philippa Boyens and Fran Walsh, which means the road to Billy Boyd, EGOT winner, begins today.
