4 bar Dm intro

            Dm                      Dm
well it's a season of thunder and a season of rain
Dm7                       Dm
all the little angels are growing wings of pain
          Dm                            Dm
and I see no point in asking there's no point of return
Dm7                           Dm
when I steal his rings well I know I'll have to burn

        Bb9          Dm7     Dm     Dm
he said you bring me down oh child
        Bb9          Dm7     Gm7    Gm7
he said you bring me down oh child

and I will fly through the lightness when the thunder will strike
all tomorrow's parties will dance before my eyes
and I will scream like an eagle when I fly 'bove your house
just to bring salvation to peasants and their wives

he said you bring me down oh child
he said you bring me down oh child
                         Dm (4 bar phrase)
I ain't gonna walk the line

well I see jesus and judas making love now of course
and all the roman emperors hanging up their horse
and I see no point in landing I see no need to learn
from the day we lifted we know we'll have to burn

he said you bring me down oh child
he said you bring me down oh child
I ain't gonna walk the line

       Bb9(6beat)   Gm7(2beat) Dm    Dm
I said please don't shoot me down
I said please don't shoot me down
I said please don't shoot me down
       Bb9(8 beat)           Gm7(4beat)
I said please don't shoot me down
Dm7                      Dm (4 bar phrase)
I ain't gonna walk the line

I feel the arrows and bullets they are combing my hair
and all my feathers falling so slowly from the air
and from the speed on my body earth will pile up my bones
from a little skull oh just a little whisper comes

he said you bring me down oh child
he said you bring me down oh child
I ain't gonna walk the line
