PUPILS will next month take part in a record-breaking Simultaneous Sing, raising money for a national cancer charity. It hopes more than 100,000 young people will participate, creating the world’s largest simultaneous choir. The children will sing a specially composed song at 2.45pm on December 9, and be radio-linked to other choirs. Money raised through sponsorship will go to Sargent Cancer Care for Children.
