These are tunes that to my ear, live somewhere in between Moldova and Appalachia.
There is a lot of commonality (and differences) between old time and Klezmer etc, but a lot are in 2/4, are played for dances, have 8 or 16 bar parts and follow similar maps (AA,BB or AA,BB,CC etc). The downbeat is emphasized in Moldavia and the upbeat in Georgia (USA). But to me, a dance tune is a dance tune and it's fun to play with the styles.
I've also decided that I can pass for an old guy in either genre.
