Unless Bono's done the heroin imitation on any other recorded performance then this is the performance that hte following story pertains to:
When I first started getting into U2 at 13 or 14, Bono was on that show on PBS..Charlie Rose? Or something like that, whatever it's called and I was watching it and they showed a clip of Bono doing the heroin thing, and I was just so entranced by it for some reason, and it's always been an image of Bono that's stuck with me, and I finally saw Zoo TV all the way through a few months ago, and it didn't click until someone started this thread, that I finally found the video of Bono doing that, and now I feel dumb, but I'm excited because I found the video, I always wondered where that came from....
Anyway, long random story moment over, this is my favorite performance of this song, and I think I like it more than the studio version.
