Lyrics:

who's that knocking on my back door tonight?
who's that knocking?
who's that knocking, got their eyes on you?
who's that waiting, standing at the corner?
who's that waiting? seen that face before
who's that walking, silent in the shadows?
who's that waiting, got their eyes on you?
who's that laughing, down the midnight telephone?
who's that laughing?
told that you were dead
who's that laughing, down the midnight telephone?
who's that crying, got their eyes on you?
