As far as I know this is a Banjo festival, in memory of Johnny Keenan, a member of a famous traditional music family, which included Paddy, Uileann Piper of the Bothy Band among others and another brother Brendan who plays whistles mainly, but also pipes I think. Sadly Johnny died a few years back.

I've never been myself, but I've heard good reports. As for the people like anywhere else it depends which ines you meet. But we're usually nice to tourists!
