(Photograph) - With one voice: all 370-plus children who attend Falcon middle school in Sprowston, Norwich, will be performing at the Royal Festival Hall in London on Monday afternoon. The school will close for the day so that teachers and pupils can take part in the week-long National Festival of Music for Youth, sponsored by The TES. The choir will sing a cantata, written by music co-ordinator Tony Bailey, based on the parable of the sower. The singers will be accompanied by Mr Bailey on piano and their own percussion consisting of Pringle box drums and maracas. Photograph by JANE HARPER
