Jones was born in Colwyn Bay, Wales. The family home was named "Bodchwil". His father was stationed with the RAF in India. When Jones was four-and-a-half, the family moved to Surrey.

Jones was educated at the Royal Grammar School in Guildford, where he was head boy in the 1960-61 academic year. He read English at St Edmund Hall, Oxford, but "strayed into history". He graduated with a 2:1. While there, he performed comedy with future Monty Python castmate Michael Palin in The Oxford Revue.
