Children around the country are being invited to sing for The Queen at her Diamond Jubilee celebrations.
Children aged between 10 and 13 in choirs are allowed to enter the competition which is happening at St Paul's Cathedral in London.
The winning group of 40 children will get to sing for The Queen in June.
Everyone has to audition by singing the same song. As Hayley's been finding out, some are excited but others are nervous.
