Paul has revealed he once recorded a secret Christmas album “just for the family” that “gets brought out each year” at the McCartney household.
“Years ago I thought, there’s not very good Christmas records,” he told BBC Radio 4’s World at One programme.
“So I actually went into my studio over a couple of years and I made one.”
Paul said he would never release the demo of traditional Christmas carol instrumentals, despite it being popular with his children and grandchildren.
“The kids like it,” he told Sarah Montague. “It’s something they’ve heard through the years, you know, and now it’s the grandkids getting indoctrinated with my carols record.”
Paul has five children and eight grandchildren – six boys and two girls.
