Some of those outfits do look Scottish, but the kilt seems to be common across many cultures. A friend is quite in medieval music and you can find a lot of it online now. I think the internet can be good for preserving culture and bringing people who share an interest together.
One of my bands plays old music and we have played for some druids. People have always been into music and we should appreciate that.
