A little narcotic warm on me 
Ab                                  Eb
what will I do without the weight of you. 
Bb            Fm
Funeral singers wail 
Ab                                 Eb
charity fails whose child are you now
                 Bb                                            Fm
The lighthouse keeper grazed the lip spread like a fog
                                                       
stood in the weather and prayed for a push
            Ab                              Eb
but doesn't take the jump again tonight.
