A musician has set himself the challenge of forming a full symphony orchestra from strangers he meets on the London Underground. Shaun Buswell, who cannot read music, will then compose a work for the orchestra to perform at one of twelve top London venues on 12 December 2012. The 12.12.12 Challenge aims to raise funds for Music4Life, a charity project run by Kick4Life, which helps disadvantaged children in Lesotho, southern Africa.
