We had a slight problem with this song at a birthday party when I was stationed at RAF Cosford in 1976. There were several visiting airmen on courses from all over the world who had come to the party, and when the Zulu Warrior chant began, aimed at the guy whose birthday it was, we had a heck of a job persuading one of our African friends not to go forward - but as he said, he was a Zulu warrior!
