Sorry if this has been posted before; I did a search of the forums but didn’t see anything on it.
There’s a new documentary out called “Closing the Circle” that takes a look at the Willie Clancy Summer School (filmed in 2003, I believe). Includes interviews with Paddy Keenan, Sean McKeon, Noel Hill, Martin Hayes, Zoe Conway, and nice footage of sessions, concerts, and classes. A few snippets of singing too, including the great Scottish singer Ann Martin from Skye.
The production is a little amateurish (sound and video are not quite synched, at least not on my copy of the DVD, and the video is sometimes a little jumpy), but I found it enjoyable overall.

I bought my copy from Ossian USA (www.ossianusa.com), so it’s definitely available in the US and Canada.
