Lyrics
I was just thinking about the way it's supposed to be
I'll eat the plants and the fruit from the trees
And I'll live on vegetables and I'll grow on seeds
But I don't eat animals and they don't eat me
Oh no, I don't eat animals 'cause I love them, you see
I don't eat animals, I want nothing dead in me
I don't eat white flour, white sugar makes you rot
Oh, white could be beautiful but mostly it's not
A little bit of whole meal, some raisins and cheese
But I don't eat animals and they don't eat me
Oh no, I don't eat animals 'cause I love them, you see
I don't eat animals, I want nothing dead in me
A little bit of whole meal, some raisins and cheese
I'll eat the plants and the fruit from the trees
And I'll live on vegetables and I'll grow on seeds
But I won't eat animals and they won't eat me
Oh no, I'll live on life, I want nothing dead in me
You know I'll become life and my life will become me
You know I'll live on life and my life will live on me
