I am in the States, Utah to be specific. While it's not exactly a hotbed of Celtic music, there are at least a handful of good bands here. The local acoustic music association advertises a "Celtic Jam" that is held monthly (or is it weekly?). I probably should go to a few of those (without an instrument) to hear what they play. I'm not so familiar yet with the tunes that I could name more than a dozen from hearing them. I can see I'll need a lot more practice and experience before I'm ready to join in, though.

Thanks again,
Jon W.
