An ancient Gaelic tradition relatively recently contributed to the English language: song syllables with no meaning at all. (The Irish were the main promoters of this.) In English today they're called "vocables."
You'll find them in Gaelic songs older than the English language -- and so formally established one can instantly identify the song by its vocables.
Right. So then...
“Ring-ding, diddle-iddle-eye-dee-oh, ring-dong, diddly-aye-aay-oh”
Name that tune.
