I went for a walk earlier, and a farm just by here has very recently got a couple of pigs and as I passed by, the pigs were rootling and oinking and making this kind of a song that went, “oink oink uhrrrrrrrrrrr… oink hoghog uhrrrrrrrrrrr…” with the uhrrs quite tuneful, which delighted me.
A piece of light music evoking a busy scene with vehicles and pedestrians all mushed together, the repeated harsh sound representing a loud traffic horn. Sorry, not much help there!
