La puerta verde

Another sleepless night.
Another night that slips away.
What's behind that green door?
An old piano plays cheerfully
behind the green door.
Everyone laughs and I don't know
what's happening behind the green door.

I won't rest until I find out
what's behind the green door.

I knocked, and when they answered
I said, 'Ah! They called me.'
Laughter, and then they kicked me out.

All I could see was many people having fun there,
and amidst the smoke, everything was blurred.
I wish I could be on the other side of the green door.

Another sleepless night.
Another night that slips away.
What's behind that green door?
What's behind that green door?
What's there?
