John was born in New Cross, London, and studied at the Woolwich Art School, the Camberwell School of Art and the London School of Printing. He arrived in St Ives in 1965, and has remained since, collaborating with Roger HILTON on his book Night Letters (1979). His attitude is one of independence from mainstream groups and styles, and prefers an eclectic approach to art, with mixed media and found objects being incorporated in his pieces.

He continues to exhibit in St Ives in group shows and at the Belgrave Gallery.
