This is the first episode to feature the song "Make Your Own Kind of Music" by Mama Cass, which is heard in many later episodes. Lindelof picked the song as it reminded him of his childhood, as his mother "used to listen to on Sunday mornings, when she’d put on music, vacuum and cry."[1] Lindelof also declared that the song "lyrically felt right", and had a haunting feeling due to Mama Cass' personal history.[5]
