Walker, 30, performed the new songFor Those Who Can't Be Here,accompanied by the 39-year-old duchess playing the piano, in a prerecorded segment shown during the Westminister Abbey event broadcast from London on ITV on Friday.

Walker said he had kept the performance a secret even from his mother.

"She was in floods of tears watching it on the telly," he told the BBC. "It was beautiful."

Walker had performed at a charity event in front of the duchess, and when asked to play at the carol service, he offered to perform a song the public hadn't yet heard.

"So I sent it over to the team and they absolutely loved it, and then a week later they came back and said, 'Um, would it be all right if the duchess played along with you?"' he recalled. "And I was like, 'What?"'

The pair rehearsed for a few weeks.

"She picked it up so well, it's really not easy to go from not playing with other musicians for like 10 years to jumping straight in with like a whole band you've never met and camera crews doing live takes that's being filmed in Westminster Abbey, so I thought it just went so well," he said. "She's [a] very talented musician."

Kate and Prince William spearheaded the program, Royal Carols: Together At Christmas.The event was attended by those who had spent time with Kate and William during recent engagements.

Walker rose to fame after the release of his single Leave a Light Onin June 2018.
