Considering the fact that U2 had a massive ticket fiasco and most people in attendance will have paid an excessive amount to see them play, will this dictate WHAT will be played? In other words, are they fearful of playing obscure songs for fear of crowd reaction? I know this is not how U2 thinks of their setlist, but then again, they've never been in this position before. I'm sure they will be very sensitive to what their audience will want to hear. Will they simply count on the songs that have worked in the past for fear of rocking an already shaky boat? Just wondering.
