I had learned the sitting-down version of clogging though. There was a quasi-local fiddler at the time (next county over) who played that way, and he was able to explain it well enough - and he could slow down sufficiently that a beginner could see the exact foot/leg movements involved (we didn't have half-speed videos back then) so he helped some of us other fiddlers in the area to learn the technique. We didn't do it on every tune or anything like that, it was just a sort of a special thing on certain tunes (predictably, most were French-Canadian tunes which, for some unknown reason, were sometimes played in my area) where it seemed to really fit.

Good points.
