" But how do such bands get there? "

The sad truth is that some bands and musicians never do. We stopped going to our local folk dance club because the resident musicians always played everything far too fast. The dancers could hardly get their feet off the floor, and went shuffling round like a sand dance.

Another thing I've noticed is the more musicians you've got, the faster they play and the more they tend to speed up.

And don't even get me started on morris bands.
