You state as "fact" that it is strange and out of the ordinary -- if there were more singers, you'd see it more often and wouldn't have the opinion that it is strange and unusual.
To many, nothing is more strange and unusual than seeing a Chattan in a raincoat with his eyes closed, shuckling and crying under the Chuppah. But that's just an opinion....the unaffiliated would ask why is he upset and expecting rain inside
Obviously, I was referring to a normative Orthodox Jewish Wedding. Saying that the Chassan looks strange in a raincoat is for a non-jew who is not expecting that. For that matter he may find the strange hats and long beards to be strange and unusual too.
Normal and
strange are extremely subjective. In an indian tribe it may be totally
normal to jump around with face paint and howl at a wedding. We would consider that
strange if we saw that at an Orthodox Jewish Wedding.
Therefore, since most Chassanim do wear a raincoat and shuckel and daven etc., that is what is
normal at an Orthodox Wedding. That being said, while putting on a concert may sound beautiful, it is not
normally done. I'm not convinced that if there were more singers out there you would see it more often.
I agree that the Dentist analogy was off, but how about a good dancer? My point is that this is the last place to be doing your 'work' and the best place to just focus on the moment.
