Stavros Flatley are earning up to £200,000 (€221,000) a week.
The ‘Britain’s Got Talent’ finalists – who fuse Greek and Irish dancing into a comedy routine – are performing up to four times a day, with each 20-minute slot netting them £10,000 (€11,000).
The father and son duo are also set to cash in further as the festive season approaches.
A source close to Demetrios Demetriou, 40, and his son Lagi, 13, said: “Stavros have performed all over the UK.
“They’re very popular at sporting events and with the Christmas party season coming up, they’re sure to be in the money well into next year.”
It is also believed the duo will appear at ‘Britain’s Got Talent’ supreme Simon Cowell’s forthcoming 50th birthday party next month, though it is not clear if they be paid more than their usual fee for the event.
They already appeared at a surprise early celebration for the music mogul, hosted by his ex-girlfriend Jackie St Clair, in July.
