“Pea-NUUUUUUUUTS! (They’re jungle-fresh)”
Remember that advert? (I think it was an advert, anyway.) This is the song – and when I was a kid, we all used to sing it. Eric Morecambe sang it in a skit.
And it has been covered more than 160 times, so I imagine EVERYONE has sung it at one time or another.
So, yes, this is a classic pop earworm. There’s hardly anything to it but it stays in your mind.
