Overview:The Arctic Monkeys don't do ad-libbing, they don't do crowd interaction, and they don't do encores. A lot of people don't like them as a live act for this very reason, but if there are any disappointed punters in the crowd tonight, then they're keeping quiet. It takes a certain kind of band to move every member of the audience at the main stage; but everyone from the front row all the way back to the tents is on their feet, delighted and singing in anticipation, even before the Monkeys begin.
