Down in the smoke in Berkeley Square –
Sans nightingale, at J Walter T –
Then the Prince of Wales -they took me there
To see the famed Sweet Charity.
It’s what they did then, dontchya know,
Them swanky London advert men:
A Mayfair lunch, a West End show –
All funded by fifteen per cent.
The rhythm of life is what we had,
Nothing was really better than this.
Me, a big spender! Look at me, Dad!
Getting a glimpse of a life of bliss!
Boadicea's Chariot 
Juliet Prowse, a national treasure back in the day. I’m pretty sure that she did the cabaret scene down here in perhaps the late 60’s early 70’s, a favourite of my mother if I remember correctly.
Yes, I think it was 1968 when I saw the show.
