The hall of Hellesdon High School was full to bursting with pupils, staff and more than 1,400 kazoos this week as they attempted to set a new world record. The popular musical instrument, renowned for its buzz in everything from classical and popular music to children's birthday parties, was used for the record attempt at lunchtime on Thursday. After a 10-minute practice, all 1,475 pupils and teachers hummed out a rendition of Pharrell Williams' hit song Happy. Matthew Brown, head of performing arts at Hellesdon High School, said: 'We were approached by Heart FM to attempt the record on Make Some Noise Day, which raises funds to help disadvantaged children and young people.'On the day of the world record attempt all the students were geared up, excited and ready to go; the biggest thing was the logistics of getting everyone together in one place at the same time.' The world record attempt is awaiting verification, but the school is very confident that the record for The Most Number of People Playing the Song Happy, By Pharrell Williams, On The Kazoo At The Same Time, will be theirs. Gerard Batty, executive headteacher at Hellesdon High School, said: 'It celebrates the trust and confidence the Hellesdon High Community has in each other and raises money for Nelson's Journey, a wonderful charity which has such a positive and lasting effect on so many young people.'The World Record for the Largest Kazoo Ensemble was set on March 14, 2011, when an audience of 5,190 formed a kazoo ensemble in the Royal Albert Hall in London as part of Red Nose Day. Accompanied by the BBC Concert Orchestra and led by comedienne Sue Perkins, the ensemble hummed-out renditions of Wagner's Ride of the Valkyries and Eric Coates' Dambusters March.
