I've been searching everywhere for the name of a song that haunts me. It starts like this:

Don't the trees look great tonight, like black lace on a fading sky
And the sun's gone westward on her run
Leaving me behind with deeds undone
Old tracks covered by new snow, pull up my shallow roots and go.

A man sings it. Came out in the late 60's early 70's.Does anyone know this song and who sang it.

Thanks
