If you haven't seen Stephen Gough before, you will in this programme, in fact you will probably see a lot more of him than you'd like.
England is renowned for its eccentrics. Elton John is an eccentric. The Marquess of Bath is an eccentric. Can the same be said, truly, of a man who walks the length of the country naked apart from boots and rucksack?
This 50-minute documentary directed by Guy Gilbert tries to get inside the head of Stephen Gough, the man known as the Naked Rambler. It speaks to the man himself, to his estranged wife, and to his elderly mother, the latter of whom complements her son's appearance by hiding her face, although when he arrives at her house, she relents.
Stephen Gough was briefly in the marines as a young man, after that he joined the Unification Church; he also married and fathered two children, whom he hadn't seen for over six years on account of his lifestyle, which includes spending six years in prison. They are reunited here.
In this programme we see him arrested more than once. He first started going naked when he lived briefly in Canada, something that became progressively worse.
Is he mad? Not according to the late Thomas Szasz, but you can make up your own mind, just don't ever again criticise Moslems for wearing the hijab.
The Naked Rambler is currently on BBC iplayer, but won't be for much longer. You can also find him on YouTube.
