Sorry, brothers and sisters, I can't answer any of the technical questions about dancing and hats. As for sunburn, we're not all that worried about the rays, so it wouldn't be that. The Honorary Chieftain was given this great blade, and he stepped to the four corners of the official dais and touched each corner. I was in the dark about this too and though I'd better not giggle and spoil the moment for someone to whom the performance might have had some great significance. At the time I didn't ask, so the moment has passed. Maybe it was all made up. (I suspect so.) Still, it bestowed a moment of gravitas. The poor chap, a Government cabinet minister in charge of the earthquake recovery, has had to put up with such a lot of flak recently, so I hope he had some fun with it.
