"One very windy morning, while I was playing at Windsor Castle, my kilt was blown up and, being a 'true Scotsman', I was briefly exposed".
"Later, while I was escorting Her Majesty, she asked me if it had been a particularly cold morning."
The royal piper also spoke about the Queen's kindness to him and his family after his wife, Morven, was diagnosed with terminal cancer.
The couple's children were cared for by the royal nannies and were allowed to stay at Balmoral Castle, while Mr Methven cared for his sick spouse in hospital.
The Queen, who had told him to put his "family first" after the diagnosis, also sent a basket of strawberries and muffins to the nurses on duty at the hospital.
He said: "I was standing with the Queen and she said, 'if you’re not here in the morning and you don’t play the bagpipes, then I know you’re away. Don’t wait to ask anyone, just go home if your family need you because it’s family first'."
He added: "She grabbed me by the arm again and said, 'you know Pipes, if anyone has a problem with that you tell them that I said it was OK to go'."
The Queen's former Pipe Major, who had played the bagpipes at Windsor Castle, recalled an incident in which the late monarch joked about it being a "particularly cold morning" after the wind blew his kilt up in front of her.
