Several years ago I had to interview him following one of his charity walks through Essex. He had a canned line: “Yes, we might have slowed some traffic down, but if the people of Chelmsford were a bit late getting their Sunday lunch, they can rest assured it was all for a very good cause.”
The intonation was uncannily close to:
“Yes I’ve hit the odd copper, yes I’ve enjoyed the old dooby, but will you piss off and leave me alone, I’m walking to John O’Groats for some spastics.”
