A ROLLER disco to help raise funds for a school trip to Cambodia is being staged this Sunday (June 29). Year 11 Tavistock College student David Jones, 16, has organised the disco to help raise funds towards the trip which is taking place next year. More than 20 students are travelling to Cambodia but as the trip costs approximately £3,500, the college has been working with the youngsters to raise funds. The event takes place noon to 4pm at the gym in the college for 11 to 18-year-olds. The cost is £5 to include skate hire.
