According to that blurb, some poet called... Although I was never a big fan of poetry at school, I certainly wouldn't call this piece of work "blurb" done by "some poet" - in this case, John Betjeman.
Although he was Poet Laureate until his death, it seems he was into more than just poetry.
Like many here on Ukastle, he was concerned by the loss of our architectural history and the often needless but officially sanctioned destruction of the past (a bit like some of the PFI schemes of today). This march of progress was something which was very evident in our towns and cities in the 60s and 70s.
He was a founding member of the Victorian Society and was considered instrumental in halting the demolition of St Pancras station and other buildings.
In some respects, his despising of the then uncommon SOX (or should that be SO/H), which was steadily replacing tungsten, mercury and even gas lighting is understandable.
Despite its efficacy, most people have always disliked its colour, its ability to monochrome the life out of our streets.
Although "yellow vomit" is a strong adjective to describe sodium lighting, (which to many of us on here is now almost an endangered species) at the time such musings were quite typical of Betjeman's style. If you think sodium streetlamps had a rough time under John Betjeman's pen, it is worth reading his 1937 poem called "Slough".
Interestingly, streetlighting is a surprisingly common topic in contemporary poetry with some of it being quite good.
