Tradition!

That song was so off. Tevye lumps together mitzvos with minhagim into one category, whereas only the latter applies. I suppose "Commandments!" is less catchy.

To our benefit or detriment, Fiddler on the Roof is for the rest of the world an image of orthodox Jewish life. 

I know a non-Jewish woman who expects all aspects of Judaism to perfectly mimic Fiddler, to the point that a man's Shabbos bekechel should be patched and worn. She calls shadchanim or any female over 50 (because they must also be matchmakers) "Yentas." Such as, "She will be your Yenta."

R2 adores "If I Were a Rich Man" strictly because of the mooing cow at the end.  "Moo the cow!"

As a kid I was terrified of the Dream scene, and even now, after seeing it, I can't bear the dark. The kinfauna handle it better than me, actually. 

I once saw a clip of Zero Mostel as Tevye, and he was terrible. Not heimish at all. His "bida bida bida bum"s were more like "hipa hipa hipa pum"s.

I saw Alfred Molina on Broadway, and he was  nearly as good as Topol (nearly as good, but Alfred Molina can play anything). Time magazine had a review, and I always remember this bit:

But when his third daughter chooses a husband outside her religion, he can debate no more. "There is no other hand!" he cries. From Mostel's mouth, it was a howl to the heavens; Molina spits it out abruptly, angrily. He's not suffering for all Jews; he's one man drawing an ethical line in the sand.

Topol's Tevye had a similar reaction. He roars "No! No! No!" and angrily stomps away, closing his ears to his daughter's weeping. I always found it interesting how Tevye, an unlearned man, was able to accommodate his other daughter's unorthodox (not unobservant, but non-PC) marriages, knowing of no halachic reason to say no, whereas here he is firm. 

Here is my favorite, "Sabbath Prayer." My family doesn't bensch the children every Friday night, but many families do. It never fails to make me sniffle.
