U2 and The BBC show Sky Arts How to Broadcast a Festival Headliner

Sky Arts could learn so much from the BBC about how they go about broadcasting a festival and in particular the headling acts. I've already posted the Bruce Springsteen set shown on the BBC from 2009 and now it's the turn of U2. Once again almost an hour and a half was shown from their set.
