FWIW, here are the lyrics as sung by Cosmotheka (Dave and the late Al Sealy). These agree with what odd scraps I can rememeber hearing as a youngster, and are rather more Englsh. (Who was Burt Turpin?!)

The Sultan sat on his oriental mat, in his harem, High Street, Persia,
He took a sip of coffee, just a drip, and he said to his servant Kersia,
"Oh, curse ya, curse ya, curse ya, it's the horrible-est coffee in Persia!"

Chorus
What I want is a proper cup of coffee, made in a proper copper coffee pot,
I may be off my dot, but I'll have a cup of coffee in a proper copper pot.
Tin coffee pots, iron coffee pots, they're no use to me!
If I can't have a proper cup of coffee in a proper copper coffee pot, I'll have a cup of tea!"

In days of old when knights and days were bold, and whiskey was much cheaper,
Dick Turpin rode to a coffee house and showed his gun to the coffeee house keeper,
He said "Stand and deliver! Good heavens, I'm all of a quiver!"

Old Bonaparte found that he was in the cart when he lost that Waterloo fight,
He gave his sword to Wellington the Lord, and he said "You British, you can fight!
You've had your Waterloo, sir; now what am I having with you, sir?"

King Solomon with his queen would carry on, so we read in ancient scandals,
He bought her lots of silver coffee pots with diamond spouts and handles,
"But," said the Queen of Sheba, "I'd rather have any old tea-bar!"
