It was lots of fun and a big success - lots of people seemed to be having a good time. Most of the time we had about 30 people dancing in two short lines. The band had various combinations of 4-6 fiddles, several penny whistles, 2 accordians, a guitar, string base, mandolin, and a stroh violin. We were on brick sidewalk with various unevenness so there was a bit of challenge.
There were lots of onlookers and a few of them joined in. I tried to these folks to join in by they were unmoved.
Below is a brief video that someone took.
