Children and staff at an infant school in Kettering took part in a world record attempt for the most amount of people to sing one song at the same time.
Park Infant School joined thousands of people across the country to sing One World With Many Different Languages on Wednesday afternoon.
They also used sign language while singing.
Deputy headteacher Linda Griffiths said: “Taking part in an event like this is not only great fun but teaches the children the skill of signing which they may use later in their lives.”
The event was organised by Sign Health.
It was followed by themed activities in the classroom.
