Raya Yarbrough, who sings both versions, originally recorded the entire song in French under the direction of Outlander composer Bear McCreary. In the end, they decided to alter only part of the opening.
"I feared that so many drastic changes in the main title might be too jarring to the audience," McCreary said in a statement from Starz. "So showrunner Ron Moore and I decided instead to create a hybrid of the French and Scottish arrangements, a version ideal for broadcast."
"We also had concerns when we looked to the future. Our characters would not spend the entire season in Paris, which meant that our main title would have to change again before the season concluded."
The original soundtrack for Outlander: Season 2 debuts on October 28, and is available for digital pre-order on Amazon and iTunes starting October 3.
