Delighted to see other examples here
One thing that always amuses (and confusees) me is to compare these performances with the high kickers presented by Riverdance and Comhaltas as 'traditional dancing' as 'traditional' with the sean n?s dancing styles.
I remember an elderly fiddle player/dancer telling a young learner "The secret is to keep your feet as near to the ground as possible" all the time you're stepping - I can do to a club in Dublin if I wanted to see legs".
I'm not a dancer, but we spent a long time interviewing musicians talking about the dances (in the old days all held in the farmhouse kitchens).
Around here there is a fascinatin tradition called 'battering pots' where, when a flagstone floor was being laid, a vessel such as an iron por was carfully placed under the floor so that the dancers would have a hollow spot to dance on and make a ringing sound as they did.
We were told that an earlier practice was to use an animal's skull for the same purpose.
I found out later that the practice once extended to Wales; social historian E Estyn Evans reports of the finding of seven horses skulls found under the floor of one Welsh house being demolished - fascinating stuff!!
