I found this quote at http://www.chico.mweb.co.za/art/2002/2002mar/020328-little.html
There was a war in Africa. Eyetalians in aeroplanes were dropping bombs on Natives who only had assegais and shields. It wasn't fair, so everybody sang:
"Will you come to Abyssinia, will you come?
Bring your own ammunition and your gun.
Mossaleeni [Mussolini?] will be there,
Shooting peanuts in the air.
Will you come to Abyssinia, will you come?"
