“It’s Armistice Day” not “It’s a Mistake” by Men at Work
For 43 years, I thought the lyrics were, “it’s Armistice Day” not “it’s a mistake.” Never mind it’s the literal title of the song. I thought they were being sarcastic. That the cold war was a lip service treaty or an "Armistice Day" but really we were at war. Which fits with the song.
