Okay so I'm still getting used to this chat thing.George's version of the lyrics differ severally from my
I tell the tale of a jealous male
She was blond and and dumb and she with her Mum on the fringe of Bethnal Green
It went quite well because he fell because he fell for all her girlish charms but he wasn't so sure when he caught her out in someone else's arms
I think it was 'her cha cha cha'
The 'cha cha cha' a sort of nudge nudge wink wink euphemism for some un-named naughty part of her.
Having commented on the lyrical variations, there seem to be several recordings of the song and at least one version of the 'Strictly for Grown-ups' album with songs like Lavendar Cowboy and the Boy Scout Song censored
