There are plenty of songs that just go full gibberish with their lyrics and titles. "Ob-La-Di, Ob-La-Da" is probably the best-known example of this, but here are some others:
The Archies, "Bang-Shang-A-Lang"
The Archies, and Archie comics in general, are one of my favorite examples of cultural ephemera. I advocate the fun, bright crassness and Middle American fetishizing (now featuring a gay!) of all Archie products, and as an angry feminist, I celebrate the present-day hostile misandrist work environment!
Alvin Stardust, "My Coo Ca Choo"
I was recently flipping through a book I own about pop music, and I came across the entry for Alvin Stardust. To quote (in full) the one Amazon review of the book, "Somewhat entertaining but I did not learn anything new about anything I was interested in. Lots of trivia on non essential acts, though."
That sums this up rather well. Ain't no also-ran like a glam rock also-ran, you know?
ABBA, "Dum Dum Diddle"
I suppose my only question would be is "How do you describe the sound a fiddle makes?" I don't think I would use such a "d" sound, or in the fun and exciting nomenclature of the phonetic alphabet, a "voiced alveolar stop."
