The Choir - 15 Doors lyrics

I saw somebody in the window A light on in the hall Could I step inside for one moment And give my wife a telephone call? So sorry to alarm you I'm not gonna harm you Don't call the night patrol Just look at me shaking in the cold I've been knocking on 15 doors When you come in the morning And say "how do you do" Will you stand and stare in wonder Cause I don't remember you? I'll say, "Once I was a stranger Once I was in need, But you hid behind the door And left me shaking on your front porch" I've been knocking on 15 doors
