Stavros Flatley's didn't win Britain's Got Talent but became one of the most successful acts on the show, claiming at one point to have made two million pounds.
The bizarre and fun British-Cypriot father-son dance duo who named themselves after a combination of Riverdance's Michael Flatley and Harry Enfield's Greek kebab shop owner Stavros wowed fans with their blonde wigs, black headbands and leather trousers in 2009.
During their now unforgettable audition dad Demi Demetriou, then 40, was joined by his 12-year-old doppelganger son Lagi.
As one of Simon Cowells' 'favourite ever dance acts' they came in fourth in the final, beaten by Julian Smith, Susan Boyle and winners Diversity.
Demi said at the time: "I can’t express to you how proud I am of Lagi.
It’s not just the way he dances or the way he handles himself, but the best thing in the world is for somebody else to say, 'You’ve got a good kid'.
"I know it’s only a silly little dance and we just have a bit of fun, but I’m proud of him like you wouldn't imagine."
The duo became well known after the show with Lagi often surrounded by fangirls.
Demi who was director of an electrical business was keen to keep his day job adding: "I can still head the business and do a few bits of dancing."
"One of the hardest things I’ve done is sell the restaurant, but I did it because I wanted to spend more time with my family. Regardless of what everyone says, the food was terrible, but we were still booked out."
Soon after however Demi's electrical firm, Lagi Contractors Ltd went into administration and sub-contractors said they owed them £100,000.
Demi is said to have personally lost £180,000 when it happened with the business in debt by more than half a million.
When Demi was told he was too big for his own good, the duo participated in 2017 show Sugar Free Farm, going on a sugar free diet.
An MRI scan showed Demi's belly fat meant he risked suffering a heart attack - and he got emotional on the show in front of his son.
He said: "The doctor said it was the worst place to carry fat because it could lead to all sorts of health problems, like heart disease, strokes, diabetes and high blood pressure. I was putting my life at risk but eating less would cut my chances."
"The MRI results were a big shock as I’d never had any health issues in the past, so it was a real wake-up call."
That same year the father and son duo went as Kenzii & Aaron's date for ITV2's 'Dress To Impress' and went on Celebrity Coach Trip in 2011.
Ten years on from BGT the duo returned to the show to perform a cameo in 4MGs semi finals appearance in 2019 then returned for Britain's Got Talent: The Champions the same year.
Simon Cowell gave them the golden buzzer and Stavros Flatley said they'd split up after the final,
Lagi said: "We’ve done this for 10 years for a joke. We’ve done so many amazing things but what is there left to do?
We’ve done the Royal Variety, we’ve played in China, Monaco - everywhere.
"When we got to The Champions, I thought this was the right time to leave. But Simon Cowell told me not to quit forever. So I will return for some shows."
When Demi said the duo made more than £2 million from their performances, he later admitted it was "a joke which got out of hand".
Lagi opened a barber shop in Cyprus, and Demi recruited 17-year-old nephew Samson in his place.
Demi said: "He has a six-pack - I’ve given up getting one of those."
Stavros Flatley came in second behind Twist and Pulse for the champions shows returned for Britain's Got Talent Christmas Spectacular in 2020.
Demi now has a water sports shop in Cyprus alongside Lagi's barber shop which boasts a Stavros Flatley Museum in the toilet.
Lagi got engaged to Annika his girl, on New Year's Eve in 2020 and posted a pic of them on Insta saying: "I didn't get a trim and oh yeahhh guess what."
The couple also said they were expecting their first child in 2021 with Baby Demetriou born in April.
Lagi said that they called their daughter Xenia.
