After 7 years of planning, the Opening Ceremony of the London 2012 Olympics is just hours away.

A worldwide TV audience of a billion people is expected tonight.

However - ahead of the show, dozens of fans have been left disappointed after being turned away from going to watch the archery at Lord's Cricket Ground.

Around a hundred people had arrived expecting to get in for free because it's described as 'an un-ticketed event'.

But LOCOG say it's a misunderstanding, because ranking rounds never have spectators.
