From my perspective of growing up as a kid in the late 60s/early 70s in the UK, the whole thing bemuses me !
It is now a fairly big deal in the UK too - although it hasn't quite become as ingrained in our national culture as changing Prime Minister every few weeks has - but it certainly wasn't the case until relatively recently.
Our halloween consisted of three elements, all of which consisted of some sort of fruit or vegetable and an element of borderline abuse.
The first was what was referred to where we lived as duck apple but was called bobbing for apples in other parts of the country.
This consisted of about a dozen or so apples being put in a bucket of water, having your hands tied behind your back and putting your head in the water to retrieve one with your mouth.
Putting your head in the water is a euphemism for one of your brothers repeatedly pushing your head in and holding it down until you'd completed the mission. Fair play to them, the skill involved in holding someone's head down in the water until just prior to the point of drowning was quite an art.
Hidden amongst the selection of apples were ones that had had a small incision made in them by my Dad to secrete a coin but the downside to this triumph was that if you managed to survive the drowning attempts to emerge with one of these prizes you then had to eat the apple to claim the coin.
These weren't your fancy dan French Golden Delicious apples, though, as these were the tartest inedible cooking apples that a 1970s UK grocer could provide so it was very much a pyrrhic victory.
The second element of the 1970s halloween in our house, retained the cooking apples and the hands tied behind the back aspect but added a new one in the form of a blindfold.
You were placed in a chair, bound and blindfolded, and you had to try and catch in your teeth whatever was swung past you on a piece of string and weren't allowed to leave the chair until you'd caught something.
The "somethings" on offer were one of the leftover apples from the previous fun and games and a bar of soap.
It was considered against the spirit of the game to not take a fulsome bite attempt at whatever wafted past so half hearted attempts were strongly discouraged using the clip around the back of the head school of correction.
In an act of unexpected generosity, all of the leftover apples were loaded with a coin this time but the same rules applied regarding eating it whereas with the soap you were at least allowed to get away with just the initial bite.
Either way, you weren't going to get away unscathed in the disgusting taste department.
We may have grown up on the shores of Liverpool Bay but with the blindfolds, hand bindings and forced water immersion techniques our house was very much more Guantanamo Bay at halloween in those days.
The final element is the one which most closely resembles the modern version of halloween in the UK, namely the carved lantern.
Now, I'm reliably informed that pumpkins were introduced into the UK in the 16th century but let me assure you that in our local shops in the 1970s you'd have been as likely to come across pheasant or quinoa as you were to encounter a pumpkin so our lantern base of choice was the turnip.
Due to its density, trying to hollow out a raw turnip and carve a face into it is something that should realistically only be attempted with the aid of power tools.
The potential dangers offered by us using the one sharp knife we owned and its main role (carving the Sunday roast) being a protected occupation meant that we had to make do with regular table knives and a spoon.
The process could be measured in days rather than hours which, combined with the rudimentary tools on offer, would inevitably lead to the adoption of the "fuck it, that will have to do" approach to fit and finish that is evident in this typical effort from the period.
As for interior illumination of the lantern, again, if tealight candles were available in the UK at that time they certainly weren't available in our local shops so it was the workmanlike though more inherently dangerous standard candle that had to be put in them.
As these never fit properly into whatever mounting hole that could be fashioned with a spoon, they would inevitably fall over and the smell of burning turnip was a constant in the atmosphere of the UK for the last week of October. Or every Sunday with my mother's propensity to burn the Sunday dinner.
The nadir of the grim lantern years was 1973 when we didn't even have the candles as there was a shortage of them as people prepared for the power cuts of the impending three day week where frivolity of using candles for turnip illumination gave way to having to use them for illuminating offices as seen here.
As regards, scary halloween movies, we didn't have any that come to mind but, truth be told, we were pretty much living in one anyway!
Things are very different now and it does appear to be on its way to being on a par with what happens in the US but for my era it was completely overshadowed by Bonfire Night a few days later.
Bonfire Night in the 70s took the danger levels of halloween to another level but as it was in honour of chaotic and ultimately doomed plots at the Palace of Westminster then it was actually very much on brand for the modern day life in the UK.
