There is no contest, I guess.
"Streets" was the opening track of the 1987 album – and it was the perfect song to open (most of) the gigs of 'The Joshua Tree' Tour. The red screens, the long organ intro, the shimmering eternal guitar notes, the building up of the sound, then lights on – and there we go. As an example just watch the Rattle And Hum ersion from Tempe's desert shows.
These images were kind of copied during the 'Lovetown' shows, which were a musically re-structured appendix to the 1987 shows. Therefore you find also some awesome performances of the tune, that didn't have to be necessarily the opening track now.
ZOO TV was fine, because it played with these classic icons from the 80ies period: with the tune becoming part of a Joshua Tree part of the show – from the explosions of "Bullet The Blue Sky", through the reflections of "Running To Stand Still" with the beautiful helicopter link to "Streets", "Found" and "WOWY".
'POPmart' tried to give it new images (time warp on screen), new beats, new sounds – an excellent version, but far from the sounds of the deserts this tune originally promised. That's why I wouldn't rank it #1 then.
'Elevation' had some really outstanding versions – with the band returning to the 'old' spirit of the tune, giving everything. Just listen to the last version in 2001 in Miami, and you know, what I mean.
And on 'Vertigo' the song wasn't the same for me, sorry. Too much overweight with political messages, repetitive, being part of a staple Greatest Hits section. So, next tour – please back to your old grandezza, please!
