Clogging it

After the previous post and my reference to clog dancing, I was watching Folk America at the Barbican: Hollerers, Stompers and Old-Time Ramblers, which features a bit of Appalachian clog dancing (about 8 minutes in), a reminder that this British tradition went to the States early (pre-1800) and became a key element in the Appalachian and Ozarks musical tradition.
