Just to kill the f***er stone dead....
An Observer reporter who covered LM this year let slip in his article that Perry was Stig. I don't think he realised it was meant to be a secret, and JC and crew (not Matthew, Mark, Luke etc, but the other one) were a bit hacked off with him.
Do a search with 'Observer, Stig, Le Mans and lovely scrotum', and you should find it.
