Around 1959 I lived in Earls Court, part of London where there were plenty of Australians, in Britain for a few months and doing odd jobs around (this was long before today's work-permit hassle). They did not always like what they found and had some verses they would recite in the pubs, greeted by the Brits with embarrassed grins (grins because everyone liked the Aussies). Here are three I recall:
They say that here in England, the beer is mighty fine
It's either hot and turbid or it tastes like turpentine.
They say that here in England, the food is mighty fine
A roll fell off a table and it killed a friend of mine.
They say that here in England, the cinema's mighty fine
To tell the truth, I wouldn't know - I've been queuing all the time.
That last one dates it!
