A repeated phrase throughout the song, "all day long I'd bidi-bidi-bum," is often misunderstood to refer to Tevye's desire not to have to work. However, the phrase "bidi-bidi-bum" is a reference to the practice of Jewish prayer, in particular davening.
However, Wikipedia says a citation is needed. Is Wikipedia correct?
Along those lines, is there any significance to other lines in the song that are not English words? I thought they were nonsense syllables, but if "bidi-bidi-bum" is meaningful, maybe other lines are too.
