Triangle-playing world record attempted
More than 120 young percussionists from Cambridgeshire are attempting to break the world record for the most triangles struck at one time.
The current Guinness record of 550 was set in 2004, but the youngsters hope they can raise that to 600 triangles.
The attempt is part of a concert by Striking Together, a percussion orchestra made up of young people between the ages of 8 and 19.
Organisers hope members of the audience will help them with the record attempt.
Striking Together was set up five years ago by Cambridgeshire Music, a county council-led scheme to develop music in schools and community groups.
It is one of a number of projects forming part of the London 2012 Inspire programme, a scheme encouraging volunteers and community groups to take part in local events and link them to the Olympic Games.
The concert takes place at Wood Green Animal Shelter, Godmanchester, on Sunday.
