I'm lucky enough to have got it 4 times out of the 7 shows I've seen this tour, with each one utterly special in it's own way (in Cardiff the crowd had to sing most of it, Bono was left really emotional after MLK and still nursing a bit of a headache from hell lol).
It's seriously not outdated, it has no means of becoming 'old' sounding, timeless! And it cannot be overplayed, because it simply cannot be played badly! And maybe that's why they keep it back on occasion, Bono has to be feeling it, he has to want that particular mood portrayed... The London 2 setlist has Bad written in brackets, leaving the choice up to Bono... Maybe it's like that on more setlists than we know of, but he's just not felt it that night. Who knows? But maybe the chance of seeing it is what makes it most magical
And congrats on meeting the band, little bit of a shame that some pushy fans sent Bono back into his car though!
