now this is what i call a powerful poem ThomasHardy
Christmas: 1924

'Peace upon earth!' was said. We sing it,
And pay a million priests to bring it.
After two thousand years of mass
We've got as far as poison-gas.
yes Steve, i am sorry to offend you find you,
but i find Betjeman, light weight, i find the rhymes in the poem in question predictable,, i suppose it describes an upper class situation and tennis match accurately, all is well in the empire, the sun never sets and there are no unemplyed nasty working class miners going on strike in the vicinity of miss hunter dunn
betjemans rhymes are predictable and he has so little to say[imo] ,other than how polite, we jolly good chaps all are, betjeman appears to like to fantasise about women as   objects,

imo this poem of betjemans is a bit like a voyeur or peeping tom, this next poem of his sums him up an upper middle class snob
Here from my eyrie, as the sun went down,
I heard the old North London puff and shunt,
Glad that I did not live in Gospel Oak.
here is a quote about him from wiki
After university


Betjeman left Oxford without a degree. Whilst there, however, he had made the acquaintance of people who would later influence his work, including Louis MacNeice and W. H. Auden.[10] He worked briefly as a private secretary, school teacher and film critic for the Evening Standard, where he also wrote for their high-society gossip column, the Londoner's Diary. He was employed by the Architectural Review between 1930 and 1935, as a full-time assistant editor, following their publishing of some of his freelance work. Timothy Mowl (2000) says, "His years at the Architectural Review were to be his true university".[2] At this time, while his prose style matured, he joined the MARS Group, an organisation of young modernist architects and architectural critics in Britain.

Betjeman's sexuality can best be described as bisexual, and his longest and best documented relationships were with women, and a fairer analysis of his sexuality may be that he was "the hatcher of a lifetime of schoolboy crushes – both gay and straight", most of which progressed no further.[11] Nevertheless, he has been considered "temperamentally gay", and even became a penpal of Lord Alfred 'Bosie' Douglas of Oscar Wilde fame.[
The poem you quoted is like a schoolboy crush, immature and lightweight
