"Sweet Little Mystery" is the second single from Wet Wet Wet's debut album, Popped In Souled Out. It was released on 13 July 1987 and reached #5 in the UK charts. In the video, recorded in Gambia, the lyrics in the second verse are Didn't I come to give you a sense of wonder / Didn't I come to lift this fiery vision. Van Morrison sued the band for copyright infringement, as the lyrics in the second verse were derived from his song "Sense Of Wonder", Morrison received an out of court settlement and a co-writers credit, along with John Martyn who also received a credit, as the chorus was based on his song, also called "Sweet Little Mystery". The lyrics in the second verse were changed to Didn't I come resisting this sight of wonder / Didn't I come insisting the higher decision for the single release. Marti Pellow recorded his own version of the song for inclusion on his 2002 album Marti Pellow Sings the Hits of Wet Wet Wet & Smile.
