THE GREEN DOOR

The singer cannot get any sleep each evening, due to the sound of the music coming from the club. He tries to go there by knocking once on the green door, trying to tell the person behind the door that he had been there before, only to have the door slammed immediately ("hospitality's thin there"). Then, through the keyhole, he tries to say the possible secret password "Joe sent me"  which only results in laughter as he is again rejected admittance into the private club.
Hope you have better success in getting past the bouncers, have a great weekend.
