Since I can't watch the video, due to 3rd world internet, I'm going to venture that the restaurants did not do an original take on the source material, say, via a nicely harmonized barbershop quartet, or maybe doo-wop?
Let me guess- badly done attempt to copy the original by guys who can't rap?
Much ballyho over nothing it seems.
