of all the American U2 audiences, I think Boston gets down hardest. saw my first shows there. if not there, it'll definitely show up in Europe.
it should be the show opener. the current Miracle opener is awkward (Bono wandering on e-stage and starting the chant? where's the excitement?). start the show with the lights down and show videos of punk rock icons (focusing on the Clash obviously), then Larry sneaks onstage and starts it, the piano kicks in, Edge shows up for the riff, and then Bono shows up under the sole lightbulb singing. would be dramatic and the crowd would go nuts. plus it's similar to the last few openers where everything happens one by one (Breathe and EBTTRT were like this)
you could play the Miracle second and then do the normal four song couplet after that and everything would work.
