The video, which shows the Duchess performing with Walker, who is taking part in the hitherto unpublished Christmas song “For Those Who Can’t Be Here”, was posted on Twitter from Kensington Palace.
British singer-songwriter Tom Walker said the Duchess came up with the idea after they met at a charity event.
“We got together, rehearsed the song nine times, and then she went for a few days and rehearsed to record later.
I was really impressed because it’s one thing to play with me in the studio, just the two of us, but it’s quite another to immediately switch to playing with a live string quartet and a pianist and two backing singers.
I think we were both very nervous because we were afraid that everything would not go according to plan, but it was absolutely fantastic.”
