So this comes from a 1926 opera by Samuel (Sholom) Secunda, who also wrote "Bei/Bay Mir Bistu Sheyn," later made famous by the Andrew sisters. The fact that it comes from a Yiddish opera should not disqualify it as folk music--many of the Yiddish songs that people think of as folksongs, such as "Rozhinkes mit Mandlen" (Raisins with Almonds) also come from similar operas.
Using a web search, I found recordings currently available of "Vi iz dos geseleh" by Jan Peerce and the Barry Sisters.
