Family and friends of murdered schoolgirl Alice Gross will perform a song she penned at a Carol Service in aid of Missing People Charity on Monday evening (December 7).

The choir will perform ‘Don’t Let It Go Away’, which was written by Alice before her death last year, at the concert, which runs from 6.30pm-7.30pm at St Martin-in-the-Fields, Trafalgar Square.

Mother Rosalind Hodgkiss, who will be speaking at the Carol Service, said: “Music was Alice’s passion.

"She loved performing and writing her own music and it means a lot to me that Alice’s song will be performed by the Missing People choir."

She added: "The charity not only brings together other music lovers, but provides comfort, community and support to those who know too well the devastation of having a missing loved one.

“While Alice was missing we were helped by so many people, and through their poster campaign and their telephone and personal support, the charity Missing People was invaluable.”

Alice, who wrote and performed her own music, was missing for a month before tragically found murdered in Brent last year after the largest search operation in London in nearly a decade.

The man thought to be her murderer, Arnis Zalkalns, took his own life before Alice's body was discovered hidden in the Grand Union Canal .

The service includes moving tributes from families of missing people including Kate McCann, mother of missing Madeleine and Peter Lawrence of missing chef Claudia.

Clare Cook, Head of Campaigns at Missing People said: "This year the Choir wanted to give a voice to those who have been missing and Alice's wonderful and moving song therefore seemed a very appropriate choice.

"The charity was closely involved in the search for Alice while she was missing and tonight's performance is an opportunity for the Choir to recognise her talent and remember all of those who are missing."

‘Don’t Let It Go Away’, arranged by choir leader James Hawkins, will be performed alongside readings, with the evening to be presented by patron Sir Trevor McDonald OBE.

Tickets to tonight's performance are still available and the concert is supported by players of People's Postcode Lottery.
