it's not really an oddity. There's a rational explanation.
A long time ago I responded to a Guardian Notes and Queries query about togas and horse riding.
Now when I do a search for my name all sorts of things I have no memory of saying or writing appear, but never this one - I'm guessing because no one has ever linked to the page so it floats as a little content orphan ...
So in theory, now there's a link to it it should appear in due course - we'll see.
