The final answer: Ronnie Hazlehurst. He sang it with a swanee whistle. He did it in one take. He never got famous for it.
But you remember his tune. You hum it in the shower. You whistle it while walking down the street. That’s power.
Next time you hear that opening, give a little nod to Ronnie. He’s the real star. The man who sold the world a whistle and made us all feel richer.
And if you ever get a swanee whistle? Try to recreate it. You’ll sound terrible. That’s the joke. Only a master could make it perfect.
Pure. Unadulterated. British. Fools.
