Thank you, Joe.

And anybody else who didn't know but might have difficulty visiting the link Joe provided, here's an excerpt:

"The Scoil Samhraidh Willie Clancy is Ireland's largest traditional music summer school, held annually since 1973 in memory of the piper Willie Clancy. During the week, nearly a thousand students from every part of the world attend daily classes taught by experts in Irish music and dance. In addition, a full program of lectures, recitals, dances (céilithe) and exhibitions are run by the summer school."
