Watch HDToday. Moishe Oysher, the renowned cantor and star of Yiddish radio, stars in Edgar G. Ulmer’s musical version of David Pinski’s play Yankl der Shmid. Singing, dancing, and flashing his eyes, Oysher gives his most robust performance as a passionate shtetl blacksmith who must struggle against temptation to become a mensch. Recently rediscovered footage makes this the most complete extant version of Ulmer’s lively folk operetta, replete with an example of Yiddish swing.
