Diamond Jubilee: Singing for the Queen
On Tuesday 5 June, the Queen will attend a service of thanksgiving in London to mark her 60 years on the throne.
Choristers from St Paul's Cathedral School will be singing a specially composed song to celebrate her Diamond Jubilee.
They've been busy practising and School Reporters William and Gabriel got exclusive access to their rehearsals. They also talked to the people who are responsible for ensuring everything goes smoothly on the big day.
This report was broadcast on BBC Breakfast on 4 June.
