The song was written in reference to (though not specifically about) his wife Diane De Burgh and was released on the album Into The Light, peaking on the Billboard charts at #3 in May of 1987.
Chris de Burgh: "By the way, I've never confirmed this song to be written for Diane, ... The song describes just a normal relationship. After some time, you begin to lose care for each other, lives driving apart. That's the way it is, but doesn't reflect my personal life or my marriage at all."
