"Then somewhere in the procession an old, plaintive, masculine voice arose in a song, wavering, stumbling in the silence at first alone, until in the band a euphonium horn fumbled for the key and took up the air, one catching and rising above the other and the other pursuing, two black pigeons rising above a skull-white barn to tumble and rise through still, blue air. And for a few bars the pure sweet tone of the horn and the old man's husky baritone sang a duet in the hot heavy silence. "There's Many a Thousand Gone."
