Young people from Corby, Kettering and Wellingborough were among 1,000 students from around Britain who were at Westminster Abbey for the annual Commonwealth Day of Observance.
The young people are students from the Association of Northamptonshire Supplementary Schools.
Alaa Abouzanad, chairman of the association, said: ““We were grateful to be part of such a spectacular event. The afternoon was brilliant and we had such a good time, and thoroughly enjoyed watching the performance.
“We enjoyed watching the whole diversity of the community within the Commonwealth and it was magnificent to see everyone together celebrating the day.”
The event was attended by the Queen, the Duke of Edinburgh, the Prince of Wales and the Duchess of Cornwall and the Earl and Countess of Wessex.
Nikki Taylor, cluster co-ordinator for the association, said: “It was nice to see a lot of schools coming together on the day, all from different backgrounds. It was an educational day.”
The critically acclaimed MOBO award winner and Brit nominee Laura Mvula performed at the ceremony and a poem commissioned for Commonwealth Day was read by South African writer and performance artist Phillippa Yaa de Villiers.
