As written here a zillion times before by myself, Axver & others WOWY is now only a shadow of its former self, at best an achingly nostalgic echo of what it used to be. Being a magical tune in the 80ies, it was performed with passion, conviction and 2 guitars. Take this (exceptional) performance as an example:
YouTube - U2 - With Or Without You DVD (Live From Paris)
During ZOO TV you still had this driving force, the desparation, the restless spirit, especially during the indoor legs and 'Outside Broadcast'. From then on it become more and more, what it it today: a part of a very choreographed part of the 'show' (not a 'concert' anymore in the classical sense). The start still was a genious one – the MirrorBall man and MacPhisto carrying the tune (and so the show) home. Very impressive, but though still holding high levels with 'Shine Like Stars' and great guitar effects, it started to lose its original standing.
This uncertainty surrounding the tune became more obvious and damaging in 1997/98 when the tune was tried with different drum and rhythm backing sounds; Bono's degrading voice tried to find a new, fresher approach to sing this tune, to give it a new meaning. The 'dance with girls' performances were there, where 10 years before, you had the singer with his acoustic guitar in the darkness and a single spotlight. And the mass chorus singalong now became the defining moment, losing more and more of the tune's subtle message of loss, rage and despair.
The crowd pleaser unfortunately became a "we have to play" in the 2000s – with WOWY being a staple also in 2001, finally put to sleep for some of the late US shows (and so for the better: What's Goin' On was exactly the feeling, that the only repetitive WOWY simply had lost ...). Even worse the (management?) decision to reinsert the tune from the 2nd leg on in the Vertigo setlists, just to play the crowd please – but only with a very few versions breaking some new ground for it (e.g. Manchester, Melbourne).
The low point of course is the tour de farce we have now: WOWY being part of the rather depressive "Funeral Blues" encore, with Bono fooling around the hanging mic, losing lines, missing them, trying to croon them with a new attitude, only to release the mass chorus. A musical sacrilege, you could call this. Just give the song a rest, friends, it does need it: Stop slaughtering the tune more and more ...
