text: Side one As with Watermark, the album title opens with an instrumental title track with wordless vocals. Its title, devised by Roma, refers to two inner satellite moons around Saturn discovered in 1980, Pandora and Prometheus, that "protect and preserve the rings very much like a shepherd guiding his flock". Enya also liked the title as the association with the moon "is quite romantic".
  "Caribbean Blue" is a waltz that depicts a journey through a fantasy world. It was named by Roma Ryan, as the melody that Enya had come up with reminded her of the Caribbean. In writing about the song in 2002, Roma wrote: "As with all dreams we reach for the ideal and "Caribbean Blue" represents such a dream. The lyrics can be summed up in three words, Believe in yourself."
  Enya believed "How Can I Keep from Singing?" was a traditional Christian hymn from the Shaker sect. She chose to record her own rendition of it as she liked its melody and "very strong" lyrics. She added, "They talked about the trouble in the world, the strife, the turmoil, but at the end of each verse it simply said "how can I keep from singing?" ... I believe this in music ... at some stage you've got to try and forget the trouble that is around you".
