Jonathon Xavier Coudrille is an English artist, musician and writer. He was born in November 1945 on the Lizard Peninsula in Cornwall, an area with which he is still closely associated. His father was the artist and ventriloquist Francis Coudrill. In 2011 he founded the Lizard Stuckists.

With notable contributions in a number of fields, Jonathon Coudrille can be described as a polymath.

Coudrille started out in broadcasting at the age of 17, appearing as a political satirist on both BBC Plymouth and the local commercial station Westward Television, which gave him his own show entitled Young Tomorrow. He also worked on BBC Radio's Today programme, under the aegis of Jack de Manio. He continued with musical political satire when he moved from the BBC to Southern Television, where he was given a Monday news magazine slot, and was later the station's musical director for a period. However, his career in broadcasting was abruptly cut short by a car accident in 1972, which temporarily crippled him with spinal damage.

John (Jim) Vivian Drummond Nettles,OBE (born 11 October 1943) is an English actor, historian and writer who is best known for playing the lead roles in Bergerac and Midsomer Murders.

John Nettles was born in St Austell, Cornwall in 1943. He was adopted at birth by a carpenter Eric Nettles and his wife Elsie and he attended the local grammar school in St Austell. When he was seven years old he learned that his birth mother was a Roman Catholic Irish nurse who had been working in England during World War II. She was placed into a mental institution after illegitimately giving birth and died of tuberculosis aged 28. Nettles has never discovered the identity of his father, but did discover he has a brother and two sisters.

In 1962, Nettles won a scholarship and studied history and philosophy at the University of Southampton. At Southampton he first performed and, having found he liked acting, he was given several amateur parts.

In 1969–70 he was in repertory at the Northcott Theatre, Exeter and in the latter year had his first screen role in the film One More Time. The following year he played Dr. Ian Mackenzie in the period drama A Family at War, a role he continued until 1972. Following that he had small parts in many TV programmes including The Liver Birds, Dickens of London, Robin of Sherwood and an episode of Enemy at the Door called Officers of the Law, first broadcast in March 1978. The latter was set in Guernsey during the World War 2 German occupation and Nettles played a police detective ordered to work for the Germans and anguished over the conflict between his duty and collaborating with the enemy.
