The Princess of Wales and Princess Charlotte performed a piano duet together for a Christmas carol service.
The mother and daughter did not appear live at the Together at Christmas event at Westminster Abbey earlier this month.
Their performance of a piece of music by Scottish composer Erland Cooper was pre-recorded at Windsor Castle last week specifically for the event’s Christmas Eve broadcast on ITV1.
Kensington Palace had teased the clip ahead of the programme with a video of Catherine and a then unknown person playing the piano captioned “a special duet...”.
Narrating the video, Catherine says: “At its heart, Christmas speaks of love taking form in the simplest, most human ways.
“Not in sentimental or grand gestures, but gentle ones. A moment of listening, a word of comfort, a friendly conversation, a helping hand, presence.
“These simple acts of care might seem small but they contribute to the beautiful tapestry of life to which we all belong.”
Organisers said this year’s theme – to celebrate the ‘power of love and togetherness’ in recognition of people across the country who contribute to society – was picked because people will be able to celebrate love in all forms in a world that can often feel fragmented and disconnected.
It is understood that Catherine wanted to include the special performance to highlight the importance of connections.
As well as the mother-daughter duet, the 1,600 guests – ranging from royals to celebrities and local heroes – experienced a mixture of traditional and modern elements to include people of all faiths and none.
The Prince of Wales gave a Bible reading from the pulpit. Princess Charlotte and her brothers, Prince George and Prince Louis were also in attendance at the service.
