For the last 56 years, the Farquharson family has been serving up homemade treats to hungry passengers from The Horn Milk Bar.

The Errol roadside cafe on the A90 between Perth and Dundee has become a bit of an institution over the years, with their success traced to a famous bacon butty which was voted as the best in the world in 2012.

Starring in a Vogue photoshoot, however, was never something the family business expected to add to the memory books.

The staff and customers watched in awe as three vans filled with props, outfits and photographers appeared just 24 hours after the shoot was given the final thumbs up.

"It was a bit of a shock," owner Kenny Farquharson says. "I've got two daughters, a nine-year-old and an 11-year-old, so once they found out there were models coming along, they got dressed up and wanted to hang out."

Model Edie Campbell and skateboarder Blondey McCoy arrived on site shortly after the crew for the motorbike-themed shoot, and the family were sworn to secrecy about the event until it featured in the September issue of the fashion magazine.

Kenny's youngest daughter Gabi, who wants to study drama and modelling when she is older, was transfixed by all the action and struck up quite the friendship with Edie when they both discovered a shared love of horses.

While Gabi seemed right at home among the glitz and glamour of the day, dad Kenny says it was a rather unusual change from the cafe's normal activities.

"We got the award for the world's bacon roll some years ago, so adding that to having Vogue here has a funny ring to it," he says.

He laughs then adds: "Vogue, The Horn and bacon roll is not normally what you would associate."

Thankfully it seems word about the famous Scottish treat the 'A90 Behemoth', which has between ten and 15 rashers of unsmoked streaky bacon on a soft white roll, had spread among the Vogue crew.

"It was quite pleasing to know that although there was other options on offer, they were left. It was good to see the models were partial to a Horn bacon roll."

Opened as usual for business on the sunny July day, Kenny says everyone seemed to enjoy the spectacle with a coach full en route to a shopping trip at McArthurGlen providing a comical moment for the crew.

"The lady in charge was laughing her head off," Kenny, 44 from Longforgan, says. "When I asked what she was laughing at, she said they had all these racks of designer clothes in the car park beside the van and these ladies thought it was a car boot sale and were trying to get a bargain.

"So the jacket that is listed as £11,000 in Vogue this month, they were trying to get for £1.50. I'm afraid they didn't succeed.

"The customers were quite bemused but I think they all enjoyed it as well."

Starting life in a small shed before moving into the now famous rounded building with the cow on top, the farming family has never ventured too far from their original purpose of using local produce.

"My mum and dad - Jim and Norma Farquharson - started off the horn in 1960 and, as a wee boy, I used to clean tables there," he says.

"It was built for my mother, who was a great baker, to produce cakes and ice cream - anything from a derivative of milk because we are a dairy farm.

"And everybody loves a bacon roll so you have to make a good job of it."

Sourcing local has always been at the heart of this quaint cafe with 40-year strong partnerships with a local butcher and baker among one of the secrets behind their popular breakfast treat.

"When I was a kid, I got £40 for my Christmas and I was going to put it in the bank but my dad said to go and buy some pigs.

"I was sent off to a local farm to buy four pigs. I was breeding pigs from the age of 14 or 15 for around ten years or so. Pigs that I supplied were going to the same butcher that we use today for the bacon rolls.

"We try to buy local, we think that's the best way to go and because we are farmers so we like to know where all the produce comes from."

Taking over the reigns as the owner, with mum and dad still very much a part of the business with Norma at the cafe from 6.30am every morning, Kenny has exciting hopes for the future of this roadside institution.

Planning permission has been submitted for a £1m upgrade to move the cafe 100 metres down the road to the nearby Inchmichael flyover and open a 24/7 cafe.

This would have a new takeaway addition and a bigger parking area for cars and coaches, something Kenny says the business would really benefit from.

They also plan to keep the original vintage building which starred in the photoshoot, although a decision on what it will be used for has yet to be taken.

"We really need to take the next step forward so it is the right time to do that" he says. "One of the things going forward is the heritage of the place.

"We don't want to lose that vibe and we want to take the customers with us.

"And the cow has to come with us."
