Series composer Bear McCreary and singer Raya Yarbrough discuss their favorite musical moments from the past five seasons of Outlander. They're joined by Maria Doyle Kennedy (Aunt Jocasta), who performs an at-home rendition of "Flowers of the Forest," as well as all twelve members of the Choral Scholars of University College Dublin for a breathtaking a cappella version of the series theme "The Skye Boat Song."
