A group of 14 people surprised other diners at a busy restaurant by standing up and singing carols between each of their courses.
Before the seasonal singing session began at Carluccio’s in Berkhamsted on Wednesday, their leader asked manager Aymen Fetouak for permission, saying: “This is what we do.”
Nobody knows who they were, but Mr Fetouak said: “Their singing was absolutely amazing and just created a lovely atmosphere.
“It was one of the best shifts I have done during Christmas. I would love for them to come back.”
