Well he is a pervy old bloke, let's face it. Anyone who perpetuates the use of women for decorous puposes needs telling!
I used to work in Camden Town near the TV AM Studios and I spoke to numerous celebs, including David Frost, without realising who they were. It's not because I'm ignorant, it's simply because they look totally different in the flesh.
In Peterborough a few years ago, I almost fell over Geoffrey Archer, who lives locally and who was campaigning for a tory candidate in an election. He jumped out from behind a post in a doorway and tried to shake my hand. He in MINUTE! i am only 5ft 1 and he seemed much smaller than me.
