A tune we played in a session at Whitby Folk Week set me searching the internet. I'm never seen anything quite like this before a cross between Sword and Morris for 1 couple

I used to go Set Dancing and was told that the term Set Dance was used both to mean a square derived from quadrilles and a 'set' (fixed) step dance. When looking for the tune, this site said Metre/Rythm Set Dance. Is this a term that has meaning to Irish Musicians?

I've seen various step dances and broom dances performed in intervals of evenings of Set Dancing, but nothing like this. Is it often danced. Are there more like it. It seems odd that it's a couple dance, the display dances I've seen have been solo (Irish step, Morris jig) or sets (Morris, Longsword, Rapper). How old is it?

Anyone know anything about it.
