Lyrics:

Tears of rain run down my window pane
I'm on my own again, good evening, sorrow
Sit and dream of how things might have been
And as I close my eyes, I get the strangest feeling
Knock, knock, who's there?
Could this be love that's calling?
The door is always open wide
Knock, knock, who's there?
Now, as the night is falling
Take off your coat and come inside
Climb the stair and then I say a prayer
For someone who could share my situation
But instead as I lay down my head
I have to leave it all to my imagination
Knock, knock, who's there?
Could this be love that's calling?
The door is always open wide
Knock, knock, who's there?
Now, as the night is falling
Take off your coat and come inside
La, la-la, la-la-la, la, la-la
La-la-la, la-la, la, la-la-la, la, la
La, la-la, la-la-la, la, la-la
La-la-la, la-la, la, la-la-la, la, la
Sit and dream of how things might have been
And as I close my eyes I get the strangest feeling
Knock, knock, who's there?
Could this be love that's calling?
The door is always open wide
Knock, knock, who's there?
Now, as the night is falling
Take off your coat and come inside
Ah, ah, ah
Take off your coat and come inside
