I Didn't Raise My Boy To Be A Soldier - Peerless Quartet
The 1914 "Peerless Quartet" version is quite listenable.
While many consider this one of the earliest anti-war protest songs in American history one only has to look back to Johann Christoph Friedrich von Schiller and Beethovens 9th to see that mankind has used music to express a yearning for peace for a long time. (Ode to Joy)
