The video is a clip from a show presented in Portland, Oregon, in September 2008. I recognize the names of two of the dancers in the video from my brief foray into Sean-Nos Irish Step Dancing, Alicia Guinn and Maldon Meehan, who are dance teachers, as well.
There are some links to videos and study notes for the Clare Lancers on the Irish set dancing social network, irishsetdancing.ning.com along with notes for other sets in the Notes tab.
