Alexandra Burke premiered this song on the February 10, 2018 episode of Graham Norton's BBC Radio 2 show. "'Shadow' is basically a song that I hope most people can relate to," she told the host. "It's about getting away from someone you love but you keep going back to the person you think you're in love with and attached to, but you need to get away from their shadow and their ghost and spirit."
"(What's So Funny 'Bout) Peace, Love, and Understanding" was written by Nick Lowe in 1974. The original version with his group Brinsley Schwarz was kind of somber, but Elvis Costello made it a classic with his 1978 uptempo take.
