Pupils at a Loughton school came together with thousands of other youngsters for a special concert at the O2 Arena.
Children at Thomas Willingale School were joined by almost 8,000 other students to sing in the Young Voices Concert at the famous North Greenwich venue last week.
They sang songs by Adele, Gareth Malone and a folk song in Welsh.
Appearing alongside the children was the LSO choir, conducted by David Lawrence, the Beatbox Collective, jazz singer Natalie Williams and the X Factor's Tabby Callaghan.
