The Opening Ceremony of the London 2012 Olympics is just hours away - after 7 years of planning.

It's estimated a billion people around the world will watch it on TV tonight.

However - ahead of the show, dozens of fans have been left disappointed after not being allowed into the archery at Lord's Cricket Ground.

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