Philip Larkin ~ A one trick pony. An overrated, opinionated, librarian who was also p*ss poor poet, so far up his own arse that cleaning his teeth must have been very difficult. Made his name when there was no-one better on the scene by setting out to "shock". That he was great friends with Kingsley Amis tells you all you need to know. Wrote poetry for the pretentious which is useful, however, to drop in a quote from if you are trying to impress people who don't know better. IMHO of course.
Personally I pefer John Betjeman or Wendy Cope for pleasurable reading.
As for the sentiments expressed in that piece of doggerel ~ it may have been his opinion but I have long suspected that it was deliberate attention seeking, written to be offensive.
