45 pupils from a Fenland school were among 5,000 children who sang at Wembley Arena in London this week.
Accompanied by seven members of staff and a coach-load of parents, students from Lionel Walden Primary School in Doddington took part in the Voice in a Million concert on Wednesday March 20.
Every year, more than 100 schools are invited, resulting in thousands of youngsters singing together on stage as part of a mass choir.
The performance opens with a banner parade where every school is recognised and among the songs sung this year were 'Chosen Family'.
The concert, which is now in its 15th year, was set up to raise awareness of adoption in the UK.
Steve Abey, headteacher, said: "Taking part in events like this opens children's eyes to the world around them.
"It also gives them the chance to take part in such a huge event, because lots of children would never have experienced something like this before.
"I think it is also great to celebrate their love of music, and it's great for raising self-esteem and creating a feeling of togetherness".
He added that the Lionel Walden pupils who took part in the concert had been practicing the set list of songs in their choir lessons every Thursday after school.
Parents who attended said it was emotional and to see their children singing and having fun at the concert.
