You'd have been most welcome in The Old Empire Band, about which I've posted before. Now that it no longer congregates as such, you'd still be welcome around these parts. If you're ever in Australia around Easter make a beeline for the National in Canberra. There's lots of just about anything that can be called folk music, folk dance and folk tradition (even camp oven cookery) and you'll find lots of company in your interests. English is well supported even though we're probably even more multicultural than the US.

Cheers, Rowan
