Sarah Brightman is giving fans a festive treat with livestream event 'A Christmas Symphony', broadcast from London's Christ Church Spitalfields on December 20.

And in a sign of extra Christmas cheer, she's reuniting with ex-husband Sir Andrew Lloyd Webber for a duet.

They will perform the song 'Christmas Dream' that he and Sir Tim Rice wrote and Sarah performed back in the 1980s when they were married - Webber has even composed a new arrangement to the song just for this show.

“Christmas is my favourite time of year,” says Sarah, "This year more than ever, we all need the joy, happiness and magic this season brings. ‘A Christmas Symphony’, is my way to celebrate this special time with fans and music lovers everywhere. I have many fond memories of Christmas with my family and hope this special concert brings some new ones for you to share with yours. Have a wonderful holiday!”

Sarah and Andrew married in 1984 and were divorced after six years in 1990, but they have remained great friends.

Brightman handpicked the set by exploring various eras of the Christmas canon and will perform “Silent Night,” “I Believe In Father Christmas,” “Ave Maria,” “La Luna,” and many more. And Sarah has invited more friends to celebrate - together with orchestra, a chorister from Trinity College, Sarah's special guests are Aled Jones (the voice of “The Snowman”) and choir Gregorian.

Brightman is also partnering with the Global FoodBanking Network, to raise awareness and funds for a much needed cause in over 40 countries around the world - encouraging fans to donate at
