Repeat Am, C, G  Am, C, D for the rest of the verses.

I am the voice in the fields when the summer's gone
The dance of the leaves when the autumn winds blow
Ne'er do I sleep thoughout all the cold winter long
I am the force that in springtime will grow

I am the voice of the past that will always be
Filled with my sorrow and blood in my fields
I am the voice of the future, bring me your peace
Bring me your peace, and my wounds, they will heal

I am the voice in the wind and the pouring rain
I am the voice of your hunger and pain
I am the voice that always is calling you
I am the voice

I am the voice of the past that will always be
I am the voice of your hunger and pain
I am the voice of the future
I am the voice, I am the voice
I am the voice, I am the voice


thats what I heard. Enjoy!
