From "Starlight On The Rails & other songs," by U. Utah Phillips:

I THINK OF YOU
(Utah Phillips)

I look to see the wildflowers blooming & wonder why they seem so plain,
The springtime rides all the brown hills over, young birds sing in a silver rain,
I think of you as the night rolls by, you're on my mind the whole night through,
Far away in a lonesome city, All the time you're gone, I think of you.

And when my world has turned to sunlight,
And the dust clouds stand in the summer sky,
I'll number all the climbing roses,
Watch to see the milkweed fly.

And when I hear the soft wind moaning
Like an angel's voice from a far-off shore,
My days slip by like light snow falling,
Or dry brown leaves blown by my door.
