Not only is the slide-solo missing, the lack of it is also making Bono do the song on auto-pilot. It's just a verse-chorus-verse-chorus song now instead of a swaying adventure it always was!
And why is the slide solo so important?
1. It gives the song really it's "fat hips", makes it sway and
2. Fires up Bono to go full-throttle and therefore the songs "slides"into a beautiful climax.
Here's some proof how Bono can really go out of his mind in a song..
What a fantastic crescendo around 6:07.. and then that yell!!
See how again Edge reacts to that: he is dancing and shaking his ass off Like Chubby Checker with a guitar...
I was there that night and I remember my jaw practically dropping by this passionate version.
One of the best versions ever with Bono going completely bonkers!
