It probably sounded like a hoax...

After answering the phone call to the Cumbria Denture Clinic in Denton Holme, Carlisle, Lesa Boland could barely believe what she was hearing from the woman on the line.

The caller explained that she was calling from GQ style magazine and that they they were about to do a photo shoot with Robbie Williams – possibly one of the most recognisable music stars on the planet.

The woman said Williams, who appears in a video playing the part of an adrenaline-pumped boxer, needed a mouth-guard.

In the days that followed, Lesa’s partner Andrew Pattinson, 40, set about the task of creating the mouth-guard, which has become a key part of the video in which Williams is seen slugging it out in the ring.

“When she said they were doing a photo shoot with Robbie Williams, and they wanted us to make his mouth-guard for the video, at first I laughed and I asked if she was serious,” said Lesa, 43.

“She said ‘yes’, they were serious.”

As well as running the Denture Clinic, Andrew – a clinical dental technician – also runs Funky Gums, a business routinely making mouth-guards for competitors in the Ultimate Fighting Championship, a mixed martial arts competition.

With the Robbie Williams mouth-guard, the magazine needed the task to be completed within two weeks.

It meant getting Williams to provide an impression of his mouth’s interior, which Andrew then used to ensure the guard was a perfect fit.

Everything went according to plan and the distinctive red and white guard now takes centre stage in the new video.

Emblazoned across the front of the guard – and seen clearly as Williams grimaces into the camera – are the initials HES, standing for Heavy Entertainment Show.

That’s the name of his new album, which is to be released on November 4.

Lesa added: “We’re just a small business in Carlisle, but it’s nice to know that Andrew can make mouth-guards for somebody that famous.”

Andrew last hit the headlines after he and Lesa told how he survived an estimated 100 mini-strokes – caused by a little known condition called moyamoya, often misdiagnosed as multiple sclerosis.

His life was turned around after staff at a specialist neurology clinic in Liverpool recognised his symptoms – which included exhaustion, temporary paralysis, numbness and joint pains.

He later underwent a life-changing 10-hour operation.

The genetic condition was being caused by a narrowing in the carotid artery in his neck, which starved his brain of oxygen.

To cure him, surgeons used an artery from his leg to replace the narrowed one in his neck.
