Yeah, the E. Europe thing is a little problematic. Although our band did play Soldier's Joy in D minor on a couple of occasions. Sounded rather klezmerisch to me. The dancers thought it was pretty funny, too.

P. S.
WYS, there's a folklorist named Samuel P. Bayard who wrote a book called Dance to the Fiddle, March to the Fife: Instrumental Folk Tunes in Pennsylvania. You might wish to get a copy of it at a used bookstore. This guy has all kinds of research on instrumental folk music he collected in W. Pennsylvania. JK
