The main use of Salisbury in this country is as a type of steak, otherwise known as hamburger and pronounced as written ...
It could be called a chopped steak,
Salisbury or beef patty
No matter what it’s called
It’s always overcooked and fatty
But presumably with four syllables, sall’is’bur’y, judging by the scansion needed in that verse ... the English city is pronounced closer to two syllables in Rightpondia, sorls’bree (sorry, can’t do the IPA ...)
The infamous hunt after which berks are named, incidentally, was the Berkeley Hunt, not the Berkshire Hunt, and the first syllable’s pronunciation as in “jerk” was probably because it comes from an aristocratic surname which preserved an older pronunciation. I quote from the Victoria County History of Middlesex, published 1911:
The only pack of foxhounds to which Middlesex can lay claim is the original Old Berkeley Hunt, which ceased to hunt the county more than half a century ago and is now divided into the Old Berkeley East and the Old Berkeley West, whose kennels are at Chorleywood in Hertfordshire and at Hazelmere Park, High Wycombe, respectively.
The original Old Berkeley Hunt was formed by Frederick Augustus, fifth Lord Berkeley, who adopted orange yellow or ‘tawny’ coats for it in commemoration of the fact-stated by Smith in his MS. history of the Berkeley family-that ‘a former Lord Berkeley’ kept thirty huntsmen in ‘tawny coats’ and his hounds at the village of Charing, now Charing Cross in the centre of London, and hunted in the vicinity.
The hunt’s commemoration in rhyming slang is because its “meets” were popular days out, not just for aristocratic hunting types but Cockneys too - the VCH says:
As time went on the Old Berkeley were obliged, Brooksby tells us, to abstain from advertising their meets “in order to avoid the pressure of a swarm of nondescripts who, starting from every suburb in London, were glad to make a meet of foxhounds their excuse for a holiday on hackney or wagonette, overwhelming the whole procedure by their presence and irritating farmers and landowners, to the great injury of the hunt.”
