Pupils at a Rickmansworth girls’ school will perform in front of thousands at London’s O2 arena tonight.

Year 6 pupils at Charlotte House Preparatory School for Girls will join thousands of other youngsters at the famous venue to sing in the Young Voices event.

They are among 7,000 pupils who will perform alongside 2007 Britain’s Got Talent finalist Connie Talbot and the African Children’s Choir.

Ben Lewis, Managing Director of Young Voices said: "Every pupil should be exposed to music at an early age, whether the joy is singing, playing an instrument or loving the sound of music, the potential benefits are huge".

Music stars Alexandra Burke and Joss Stone have previously performed at Young Voices events.
