1. Musically there is no contest. Much better drums in the intro- very, very powerful. On Chicago DVD they are quite weak.
2. Stadium production, the giant screen owns all. Lot of references to Zoo TV (for example: there is video of Bono doing his characteristic poses in front of the static screen), Zoo TV/communism theme (as I said many times before- one of the coolest things U2 has ever done), Bono has a camera installed in his microphone, so we see his face on the whole screen (reminds the end of HMTMKMKM during Popmart)
IMO this is the best song from this tour. In a few minutes I'll upload the performance from Twickenham radio broadcast, but I really recommend to download some european DVD.
