Samantha Hahn was the youngest member of the critically-acclaimed National Yiddish Theatre Folksbiene production of “Fiddler on the Roof” (she played Tevye’s youngest, Beylke). She’s also an author. In advance of a NYTF book party and discussion May 2, we are excerpting from her book “On the Roof: A Look Inside Fiddler on the Roof in Yiddish,” reprinted with the permission of Pegasus Publishers. The book collects testimony of the cast, crew and creative team, shining the spotlight on the inside story of the historic production. In the following excerpt Hahn recalls entering into a very different sort of shmata business and finding her way into a new and old tradition.
