Everyone seems to play this particular tune in a very even tempo, usually trying to get it to sound very lyrical. When I first heard the tune, it was on an LP of Shetland Fiddling, and I think it was played by the bloke who wrote it (Tom Anderson). The delivery was Very stilted, akin to the style of a Strathspey (but without the very fast bits mixed in).
I think it sounds much better played with a bit of style.
Quack!
