Starz’ Outlander had its world premiere screening to a rapturous crowd of 1,500 fans in downtown San Diego on Friday night. But before the airing the first episode, Emmy-winning composer Bear McCreary (Battlestar Galactica, The Walking Dead) treated the audience to a live performance of the show’s score, including his title credits song. It’s an arrangement of the Scottish folk tune “The Skye Boat Song” — appropriate for Starz’ romantic adventure following a 20th century woman who travels back in time to 18th century Scotland.
