The Canadian version is sung as a three part round:

Don't dump your junk
in my back yard,
my back yard,
my back yard,
Don't dump your junk
in my back yard,
my back yard's full!

Fish and chips and vinegar
Vinegar,
Vinegar,
Fish and chips and vinegar,
Pepper pepper pepper salt

One bottle of pop
Two bottles of pop
Three bottles of pop,
Four!
Five bottles of pop,
Six bottles of pop,
Seven bottles of pop,
More!

Yes, they really do all fit together as a round, and is it ever a tonguetwister to sing fast!



We three Kings of Orient are
Trying to smoke a rubber cigar
It was loaded
It exploded
Now we're on yonder star...



And kids even parody their own songs: the familiar oldie

(Suzy) and (Johnny) sittin' in a tree
K I S S I N G
First comes love, then comes marriage
Then comes (Johnny) with a baby carriage!

became

Suzy and Johnny sittin' in a car
Are they nekkid? Yes they are!
The car goes zoom, Johnny goes boom
That's how they got together so soon...



BTW the version of Stella Ella Olla I heard today had two variants for one of the middle lines:

"Blow, blow, blow your nose!"

"Blow, blow, the toilet overflows!"
