This is the third UK single from New Zealand rock pop band The Naked and Famous' debut album, Passive Me, Aggressive You. Thom Powers from the band told The Weird Fishes that when he wrote the song, he was "thinking about three people. A boy character, a girl character and the girl I'd once said 'Don't you know people write songs about girls like you…' to."
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.
