I have posted this poem before but I think it is worth another reading

HAMPSTEAD GIRLS

A better class of person
Adorns the Hampstead
Red-bricks and glass
Whether lounging in the chic-lit bars
Or just lolling in the grass
Hampstead ladies in particular
Ride their bikes with elegance
And sip their foamy cappuccinos
With practised nonchalance.
On the pavements and in the cafes
There are no sightings
Of the culturally bereft
Even down-and-outs
Lean quite boldly to the left.
John Betjeman could not complain
Or call on Hampstead Heath
For bombs to rain
Nor suffer scorn like poor old Slough
Who he had deemed
Not fit for any humans now
Those air-conditioned bright canteens
In Hampstead’s glades will not be seen
And there’s plenty grass to graze his cow
Hampstead Heath’s as green as Ireland now!
