In many, many respects, I see this as very similar to "Fez- Being Born". Arguably, "Fez" would have made a terrific show opener, or at least encore opener. The beginning of "Fez" is clutter. Marketplace sounds of Morocco. "Zooropa" obviously starts the same way, and is thus a perfect, reflective album opener. Gentle sounds fade in, combined with an overload of information- obviously the theme the band was caught up in at the time.
It continues to segue into the guitar line and bass appearance later on, made apparent by Edge's wah-wah delay at 1:48. This line carries the first section into the "gentle zooropa" portion of "Zooropa" This portion seems to descend the listener into the depths of what the rest of the album is; Edge's fading wah sounds act as an escalator, slowly revealing more and more of what the next 45 minutes' sound will be like.
The guitar line appears alone again- much like Brian Eno's synthesizer segues in "Fez- Being Born"- and is the last thing heard before the faster coda of the song begins. This is where Bono's lyrics truly shine. The wah delay turns into a stuttering wah in the background as Edge's backing vocals uplift. The chorus effect on Bono's vocals bring to mind a graduated version of his character "The Fly", with a fresh head. Instead of the cynical, truism bantering Fly that we've been used to, he's now admitting that he himself has no compass or map, but that there's nothing to worry about- he'll get you both through the night.
And it is the night, isn't it. Because what would Zooropa be in the sunlight?

I just wanted to get that little bit of theorizing and writing out of my system, it's been boiling up ever since I started really opening my ear to the song.
So discuss! I want to know what everyone thinks about the tune...and really, to you- what is zooropa? At the risk of sounding like some gaudy university professor- I don't really think there's a wrong answer, really...I just want to know what it means to everybody else.
