Rotten bad luck for Alex Thomson

"If you don't want the whelks don't muck `em abaht
If you don't want `em other people may"

Ah-ha. This explains something. Earlier this afternoon I tested my new Tesla Coil for the first time. When I switched it on, my desktop computer un-screensavered and popped up a dialogue box trying to import some text from a window. I had no idea where it came from, but it was actually these two lines of the song, so it must have found an open tab and copied from that. And there I was, thinking I had had a message from beyond the grave.
 
The whelks! Are you not familiar with the musical heritage of your country?

"If you don't want the whelks don't muck `em abaht
If you don't want `em other people may"

There's a fellow you should meet, runs a fish shop down our street
He wraps it up in paper every day
When they're crowding round the stall, he addresses one and al
And this is what you'll always hear him say"

Nah, if you don't want the whelks don't muck `em abaht
And take yer baby's fingers off the slab (They're covered in
chocolate!)
Lovely two eyed kippers, take `em for the nippers
Take a hake or a nice cod steak
Soles and eels for the old man's meals
They're lovely – they're all fresh in today
So if you don't want the whelks don't muck `em abaht
If you don't want `em other people may

If you don't want the whelks don't muck `em abaht
And move yer pram and let the others in (You're blocking the doorway)
Lovely two eyed kippers, take `em for the nippers
Take a hake or a nice cod steak
Roes or trout for the old man's gout
They're lovely, they're all fresh in today
So if you don't want the whelks don't muck `em abaht
If you don't want `em other people may

"my country"?
Not many Pearly Kings & Queens down our way.
Well not exactly true, there were a few queens.
