"The care and compassion you give, often quietly and unspoken and without any expectation or recognition, make an extraordinary difference to the lives of others," Princess Kate said in the concert voiceover, as electric candles shone on the Christmas tree. "As the year draws to a close, I hope this season brings you moments of peace and clarity and that you, too, feel surrounded by the same love and care that you offer so freely."
The only-in-England concert featured Kate Winslet giving a personal reading about "the spirit of love" in the echoing Westminster Abbey and Chiwetel Ejiofor reading " 'Twas the Night Before Christmas."
