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
