I recognise it as very similar to an old Australian falloping song that I heard years ago by Ned Kelty and the Kelpies. I believe it went something like this:

Di di di dum, diddle diddle diddle dum
Diddle di day dum, diddld diddle dum
De dy de do dum do dum do
De dy de do dum do dum do

This is known as the "Rolfus Harrisus" beat.
