Tonight I had seats directly behind the stage for the first time this tour and was shocked to see that Bono had a "teleprompter"! It was on the floor directly in front of his microphone to the right. In red letters on a black background it showed the name of the song and then slowly scrolled the lyrics during the song, stopping during instrumental breaks, so there must be someone in the sound booth operating it.
One of the most interesting things was that it put up the name of the next song very early, sometimes before the song in progress was fully over. At the end of One, "Zoo Station" came up even before they had left the stage. At the end of Yahweh I was almost sure there was a 3-letter word on there for a while (Bad? Or just my imagination after Chicago 4?) - then it switched to 40.
