JJ. I've been told that Madonna began her set with the hit song 'Music' whose main refrain goes "Music unites the rebel with the bourgeoisie". I can think of hardly any other song that sums up Live8 better than this. But if the ideas of the gig goers and TV viewers must have been mixed, what of those who actually came to the protests in Edinburgh? Having spent the weekend diligently vox popping and discussing the mood there are some clear pictures emerging, of who is here and why.
