Reading through it, I couldn't quite grasp who the subject of the interview was. It can't not Bono; "U2" responds to one question: "Bono says it best..." Could it be one of the producers? After all, a producer could get away with saying "I think..." and then, on behalf of the band, "we think" (which is pretty much what happens in the article).
There're also some answers in the interview that kinda irk me, that seem rather made up... responding to a tour-related question, there's: "[there's] a new software that anyone can get called "Vertigo." Vertigo lets you make 3-D images that can be projected on to a big screen. It's stunning and its applications in a live show are unlimited." That anyone can get? Wouldn't U2 go for a more exclusive product? Plus, the fact that it's named "Vertigo" made me feel all-the-more gumshoe-y.
And then, almost at the end of the article, there's the bit that bothered me the most: "We are no doubt going into the Rock and Roll Hall of Fame very soon. It's staggering and humbling." Are U2 really that arrogant??!
To call the interview a work of fiction would definitely be premature, but... I dunno. It just comes off as a bit shifty to me.
