My version:

I TELL THE tale of a jealous male and a maid of sweet sixteen,
She was blonde and dumb and she lived with her Mum on the fringe of Bethnal Green
She worked all week for a rich old Greek 'COS her Dad was on the dole
And her one delight was a Friday night when she had a little rock and roll

Ch To my IT-fal-DAL, to my titty-fal-dal, to my itty-bitty-fal-dal-day

Then one fine day in the month of May, she met her TRUE romance,
He was TALL and sleek with a scar on his cheek and a pair of drainpipe pants
She said "With you I could be so true, through all the years to come!"
AND she loved the gay, abandoned way he chewed his chewing gum.

Ch

THINGS WENT QUITE well, FOR SOON he fell for all her girlish charms,
UNTIL ONE NIGHT he caught her RIGHT in someONE else's arms,
He said "LOOK HERE, you know, MY DEAR, this is going a bit too far"
Then he TURNED quite white and HE sloshed right in the middle of HER cha-cha-cha

Ch

HE went before a man of the law, who said, "This will not do!
I've had quite enough of the sort of stuff THAT I get from the likes of you!"
AND WAS SHE peeved when he received a longish term in clink
In a fit of pique she married the Greek and now she's dressed in mink
