This is a favourite Scottish dance tune and has quite a few different spellings, from "Neevie Neevie Nick Nack" to "Davie Davie Knick Knack" and practically everything in between.

"neevie neevie nick nack", incidentally, was a method by which "het" (or "it") was chosen in children's games, a bit like one-potato, two-potato...
