After the Britain's Got Talent live final and the tour, Stavros Flatley even got an invite to Simon Cowell's birthday party. Life has changed quite dramatically for the father and son dance duo over the last six months. Dad Demetrios says if they had known what would happen after their first audition the family might have actually talked properly about whether they should enter the show. Demi said: "Knowing what we know now we would have sat down and had a family discussion for at least five or 10 minutes." The pair are now releasing their first book just in time for the Christmas market, a tongue-in-cheek guide called How To Be A Little Bit Greek. It features tips on everything to saving money to the best way to barbecue. Demi added: "You can barbecue turkey, you know that don't you?"
