You might think that the only connection between these two erstwhile passions of mine is Wales: one is a story of dogged individualism seeking freedom, set against the backdrop of Portmerion, a peculiar citadel on the Welsh coast that is woven into the narrative of the whole show, whilst the other is a collectively-minded Welshman whose work prefigured Marx and Jamie Oliver, but when they put themselves in the American landscape both The Prisoner and Owen chose harmony as the word that would best encapsulate their American sojourn.
