The visual effects on Streets during Popmart, plus the way the song tempo is sped up and the extra bit at the ending, was always my favorite. Then there will be no time, time, no time, then there will be no...time...with all the colors turning into a dove on the screen. Amazing.
Then came Slane Castle, when Bono just wails at the beginning, to keep from crying IMO. Edge has no such luck, as the camera pans to him as his eyes well up. At the end, as the Edge fades his guitar away, Bono looks over at him, and Edge has his eyes shut as he plays out the song. That version always gets me, now, so, for sheer energy...POPMART, but for raw emotion...Slane.
