The Prince of Wales and Duchess of Cornwall rocked to Elvis at a tea dance to celebrate the tenth anniversary of the house he helped save for the nation.
Charles chatted to Elvis impersonator John Reid before he and Camilla took a spin on the dance floor.
They were attending a tea dance in the walled garden pavilion at Dumfries House in East Ayrshire attended by 45 people from local community groups.
It is part of a series of events to mark 10 years since the Prince helped secure the future of the stately home.
They also attended a garden party where they met people from the local community.
Charles spoke to Mason Kidd, 12, who is carrying out a kindness project, performing 18 acts of kindness in memory of his brother Ross who died of cancer aged two and would have turned 18 on December 1 this year.
As his twelfth act of kindness, the Cumnock Academy pupil gave the Prince a framed photo of a view of the temple at Dumfries House.
Mason said: “I was extremely nervous to talk to the Prince but happy that the twelfth act of kindness is done.”
His other acts have included taking doughnuts to the police and pizza to firemen, and leaving balls at a dog walking park.
They then went on to a dog show, accompanied by Camilla’s two Jack Russell dogs Mabel and Bluebell.
Camilla presented the best in show rosette to schoolgirl Emily Love from Cumnock who won the title with her Border Collie Lexie.
At the dog show 14-year-old Arshia Rajaby, visiting from London, approached the Prince to perform a card trick.
He said: “It was really good speaking to him, he was a very nice guy.”
His mother Afsaneh Navidinia said: “My son told me he wanted to try the card trick and the Prince was so kind, very nice.”
The celebrations are being held to mark a decade since the stately home was saved for the nation by the Prince.
Earlier in the day, the Duchess of Rothesay sat behind the wheel of a £260,000 fire engine as she joined the Prince on a tour of a company that produces emergency vehicles.

The company works with The Prince’s Trust, taking on a number of young people though their training courses and offering apprenticeships for auto electricians, coach builders, mechanical fitters and automotive painters.
Camilla was invited into the driving seat of a fire engine and shown how to switch on its lights and siren.
The couple saw how the vehicles began their journey as a basic shell before the interiors were filled with vital fire-fighting equipment.

They also saw engineers, electricians and coach builders completing the vehicles at the plant.
Camilla, wearing a lime green Mr Roy suit and Burberry trench coat, toured one side of the vast garage, while Charles, who wore a light grey suit, chatted to workers and apprentices on the other.
