Not many I would have thought.
I think the book puts a northerner's perspective on the north/south divide. I liked the fact that a woman in the south has a child with an unlikely posh name, and she lives next to a television producer, but thinks this is the norm.
I live next to a retired plumber called Brian, and my other neighbour Ken, worked on the parks department.
I was slightly disappointed with the book overall. I felt it was an attempt to be an English Bill Bryson, but a good read nevertheless, and the part about the BBC bias about the north was spot on.
Do you watch BBC weather, where there is nothing on the map from Birmingham to Newcastle? There is a Plymouth, Norwich, London, Cardiff, etc, but no Liverpool, Manchester, Leeds, Sheffield. How can this be?
But you are right, no mention of northern soul at all.
