The Only Time star was deeply touched by Ryan's poetry about the Channel Islands and recruited her as a lyricist for her eighth studio album, Dark Sky Island - the name locals have given Sark.

The singer tells WENN, "This album has a theme of journeys. Journeys to the island; through the length of a lifetime; through history, through emotions; and journeys across great oceans. So although it's not a themed album, as such, we nevertheless have an underlying connection between songs."

Dark Sky Island will be be released digitally on Friday (09Oct15).
