Going by the old song:
"There's an old piano
And they're playin' 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
Saw an eyeball peepin'
Through a smoky cloud behind the green door
When I said Joe sent me
Someone laughed out loud behind the green door
All I want to do is join the happy crowd behind the green door
Wish they'd let me in
So I could find out what's behind the green door"
it might be an old style speakeasy?
