My eldest (4) goes to a nursery which is very multinational - all sorts of foreign kids, from all over the world. It's very good but its make-up is nothing special; it just reflects the nursery-using population round here.
He knows the local team is Arsenal and he's being indoctrinated by the nursery teachers (local girls) to follow them - he recently informed us, apropos of nothing: 'I hate Chelsea'. He knows that some Arsenal players are Spanish and French just like some of his nursery friends.
I assume this is why he simply doesn't understand the World Cup. The notion of an England team makes no sense to him despite our spending a while to explain it. His biggest objection was that unlike him some of his friends wouldn't follow England even though they lived in the same place as him - this was literally inexplicable.
Do a child's horizon's broaden gradually, country coming behind other identifications? Or is this how he's always going to think, as a Londoner first and foremost - a born and bred cosmopolitan?
By the way, the title of this post gives me an excuse to refer to the very greatest World Cup song (below). It's actually the only one that's good in any way at all. It would have been a hit without the football tie-in and you can't say that about any of the others.
Its use in the current Mars advert is a great idea, I think. Not much happens: a now-tubby John Barnes (too many Mars Bars probably) does his rap - yes, still badly - and lots of people dance around him, unorganised and, it appears, spontaneously. They're in a park. They look normal - they're not even over-excited as people often are in advertland.
As was pointed out here, 'a montage of people having a good time being alive' is something the internet does very well and, as one would expect, TV advertisers are making the most of the insight. It seems you don't even need a montage: fairly ordinary people having innocent fun allied to a memorable soundtrack seems very affecting right now.
