Pupils from Sawtry Junior Academy took part in a Young Voices event at the Resorts World Arena, Birmingham.
50 members of the school choir took to the stage to sing a range of classic songs as well as pop songs, and a medley from the musical 'Matilda', and a medley from the Disney film, 'Moana'.
The choir members have been practising their singing skills with the help of their teachers since the autumn term.
They were soon ready to share the big stage with thousands of other school children from across the country.
