Green Door.

Midnight, one more night without sleepin'
Watchin', till the morning comes creepin'
Green door, what's that secret you're keepin'?
 
There's an old piano and they play it hot behind the green door
Don't know what they're doin' but they laugh a lot behind the green door
Wish they'd let me in so I could find out what's behind the green door.
 
Nothing much has happened behind this door for a long time, but at least the periwinkles have a comfortable home.
 
Thanks are due to Rainie for hosting the Derelict Sunday challenge this month.
