SAND CREEK RIVER
They've taken away our heart under a dark blanket
Under a moon dead in childhood, we slept without fear.
It was a twenty years old general
Wearing a uniform deep blue as his eyes,
It was a twenty years old general,
The son of a storm
There's a silver dollar lying on the bottom of Sand Creek.
Our warriors were too far away on the buffalo track
And that distant music grew louder and louder
I closed my eyes thrice,
I found myself there again
I asked my grandpa, Is that only a dream,
My grandpa told me Yes
Sometimes the fish are singing on the bottom of Sand Creek
I made so strong dreams that my nose started bleeding,
The lightning in one ear, paradise in the other,
And then the smallest tears
And then the biggest tears
When the snow tree
Gave red starred blossoms
Now the children are sleeping on the bottom of Sand Creek
When the sun raised its head beyond the night's shoulders
There were only dogs and smoke and overturned tepees
I threw an arrow at the sky
So that he may breathe
I threw an arrow at the wind
So that he may bleed
You got to look the third arrow on the bottom of Sand Creek
They've taken away our heart under a dark blanket
Under a moon dead in childhood, we slept without fear.
It was a twenty years old general
Wearing a uniform deep blue as his eyes,
It was a twenty years old general,
The son of a storm
Now the children are sleeping on the bottom of Sand Creek
