it seems like such a waste of time for them. they can't have that much time left as a band, and they should spend it on recording and playing new music about their what their lives and the world are like now, not diving into the past. the shows will be great though, and they'll be playing seven songs that are rarely (or never!) played so it will be pretty special. But it seems like they're misusing their position as artists and men in late middle age. Tell us what you've learned, U2!
