In 1974 a 33 year old man named George Davis was convicted of robbing the payroll of the London Electricity Board in Ilford. He was nailed on the evidence of cops who were outside the bank at the time of the robbery and was sent to prison for 20 years.

However, his friend Peter Chappell was convinced Davis was innocent and inspired by discrepancies in the police statements and the fact that none of the bloodstains at the scene matched with the defendant, started calling for Davis' release.

Over the following months 'G DAVIS IS INNOCENT' appeared on walls, bridges and tunnels from one side of London to the other, some of which are still visible today.

culminated in Chappell and four others breaking into Headingley cricket ground in August 1975 the night before a test match between England and Australia. Using plastic cutlery from a service station they dug holes in the pitch, filled them with oil and painted 'Sorry it had to be done, but George Davis is innocent'
