Trying to find an episode of thats life that featured a jumper my Mum sent in

When I search on google, the ai results seem to recognise the actual happening, but it doesn't tell you the specific episode.
My Mum bought me a mohair jumper from a charity shop in the early 80s, and when I tried it on, it didn't have a hole for your head to go through, so Mum sent it to that's life, and one of the guys put it on.
The google ai results mention the following :
"This specific "mohair jumper" story is a classic bit of That’s Life! folklore, centering on the presenter Bill Buckley.
The episode features a viewer-sent jumper that was literally knitted as a solid tube—the sender had forgotten to leave a hole for the head.
The Famous Jumper Incident
In the 1980s, Bill Buckley was known for wearing various colourful, fluffy jumpers sent in by the show's massive audience. One of the most memorable segments involved a jumper that arrived at the studio looking perfectly normal until Buckley tried to put it on:
The Flaw: The viewer who knitted the jumper had accidentally completed the entire garment without an opening for the neck.
The Presentation: Buckley held up the fluffy, "headless" mohair tube on air to show the audience the mistake, much to the amusement of host Esther Rantzen and the rest of the team".

I just found out, there's only a handful of episodes of thats life on youtube and amazingly, right at the start of the episode from 20/4/86 Esther puts on a "t shirt" which is sort of yellow, which has no hole for a head.
But, my long sleeved jumper was definitely fluffy black mohair, as I was a bit of a goth and those were worn by loads of goths in the early 80s, and I specifically remember one of the guys (not sure who) on the show putting it on.
Also the ai google results mention Bill Buckley, who wasn't on that 1986 episode.
I'm pretty sure it would have been earlier than 1986, maybe nearer 1983ish.
