This is a track from British Acid Jazz group Jamiroquai's seventh studio album, Rock Dust Light Star. There has been speculation that frontman Jay Kay is addressing on this tune the end of his romance with his former fiancée: the actress and TV presenter Denise Van Outen, who has since married actor Lee Mead. "That song is not entirely about the woman you imagine it is," he told The Daily Mail. "It's based on someone I know, but the lyrics have been switched around. It's about a girl I used to go out with, who then got married. It's a bit cheeky."
Who writes a song about a name they found in a phone book? That's just one of the everyday things these guys find to sing about. Anything in their field of vision or general scope of knowledge is fair game. If you cross paths with them, so are you.
