Lyrics:

I opened the window
You opened the door
This room needs some air
This room needs a new broom
Sun in an empty room
Sun in an empty room on the wall
I looked through the window
And you walked through the door
This room needs some air
This room needs a clean floor
Sun in an empty room
Sunlight in empty room
I opened the window
You opened the door
This room needs some air
Empty room
Empty room
Empty room
Sun in an empty room on the wall
I... open the window
