I'd heard about this TV appearance featuring Brian Clough and Don Revie, dating from shortly after Clough's calamitous 44-day tenure in charge of Leeds United. But I'd never seen it before I discovered it today via a comment on a post on the Guardian blog (h/t to one BrazilBranch). I would dearly love to see the whole interview, but even this brief clip is almost frightening: see at 1:08 how Clough says, "I wanted to do something you hadn't done". The tension is fierce.
If you haven't read David Peace's The Damned United, a biographical novel about Clough's time at Leeds, or Provided You Don't Kiss Me, a portrait of Clough at Nottingham Forest by Duncan Hamilton, allow me to be completely unoriginal and recommend them to you. Incidentally, I read the former this time last year, so I now associate Christmas with its tar-black portrayal of the inner Clough. Which can't be healthy, can it?
