Pupils at Rowan Gate Primary School in Wellingborough took part in a record breaking sign-along attempt.
They were among thousands of people across the county who took part in the attempt to have the most people singing in sign language at the same time.
It was organised by the charity SignHealth to raise awareness of deaf issues.
A school spokesman said: “A total of 160 adults and children took part at the school. It went really well.
“We have now got to send a letter to the charity to say how many adults and children took part before we find out if the record was broken.”
The record-breaking attempt took place on February 8.
