I swear to god that some of you believe there is a contingent of people on this forum who want a setlist full of b-sides and rarities. Nobody is saying they should do a full arena tour like this without any of the warhorses. I think it'd be really cool if they did do special shows for diehards, advertised well in advance, but obviously they're not the sort of band to do that. Everyone knows this, and knows that a majority of the set will be warhorses and new songs.
What I think is disappointing for some people, and fairly enough in my opinion, is the near-total absence of any acknowledgement of the diehards in what is known to have been rehearsed (which, yes yes, may be incomplete and I'm sure there will be surprises). 360 had a shit-tonne of warhorses, but it also brought back songs like The Unforgettable Fire and Ultra Violet - which aren't exactly rarities, but they had not been played live since the early nineties and fans had eagerly hoped for their return. Vertigo likewise had many warhorses in its stable, but fans flipped when The Electric Co., An Cat Dubh, and Zoo Station were played. We knew about these well before opening night.
Only a few rarities have been rehearsed, they do not at this stage seem central to the band's setlist ambitions (I am sure something has been kept under wraps), and they are generally not rarities for which there has been sustained clamour. Obviously U2 are going to write a set that mainly showcases warhorses and new songs, but I think that for a lot of people who are a bit less than enthusiastic than they expected to be about the rehearsals, they would have been sated fully if Exit had preceded Raised By Wolves or Love Is Blindness led into the intermission or Lady With the Spinning Head followed Mysterious Ways or Gone was anywhere in the main set or whatever. A couple of those. Not a run of ten songs drawn solely from Pop, October, and a 1978 demo session. Just a couple of well-placed treats (by and large not especially obscure ones either) as a nod to those fans - of whom there are many for a band of U2's stature - who have seen them many times over the years and love to dig into the band's back catalogue.
I do not think that's unreasonable. Now, if U2's kept some cool shit under wraps and we all get blown away by the encore opening with A Sort of Homecoming on the 14th, awesome. But before you trot out the "wah wah you complainers the tour hasn't begun why aren't you gushing with enthusiasm!" posts, you might want to consider what people are actually saying.
