A talented school choir have performed in an annual concert to raise money for a children’s cancer charity.

Felsted Preparatory School sent 49 pupils to London’s O2 Arena to perform in the Young Voices concert, which supports CLIC Sargent.

The choir sang with 8,000 other children from around the country and the African Children’s Choir, who helped record Gary Barlow’s Diamond Jubilee song, Sing.
