An all Yiddish production will be performed by the Australian Opera Company at the Sydney Opera House in the future.In 2019, Max Lewkowicz directed a documentary on the continuing legacy of Fiddler on the Roof. It was called: Fiddler: A Miracle of Miracles.
It does a great job laying out the enduring themes which continue to bring audiences. The doc ends with this bit of information: "Since Fiddler On the Roof opened on Broadway on September 22, 1964...the show has been performed EVERY DAY...somewhere around the world."
The DVD of Fiddler: Miracle of Miracles is currently available on Amazon for $11.99. If you like Fiddler, do yourself a favor and see this documentary.
Besides clips of many different productions/casts (including Joel Grey's all-Yiddish production), there are interviews with Harold Prince, Jerry Bock, Sheldon Harnick (I went to college with his daughter!), Joseph Stein...and many, many more. It is really wonderful (despite one unfortunate segue into contemporary politics).
