Riboin from Beri Weber, sung acapella in the above clip by Daniel Eleff.
He also composed "Lo Yaavod" for Yaakov Shwekey, and some others that I can't recall offhand.
Daniel Eleff is Benny Friedman? I once heard Benny give a shout out to Daniel at a concert. They can’t be the same person. I see you are credited with lots of “hat tips” in your profile. If are right about this double life theory, that might count as another hat tip. Im just messing, thanks for the info! Even though it’s unrelated to the nutritionist inquiry, I’m guessing the more active this thread is, the more likely I’ll get more info about the original topic.
