When/Where Was This Picture Taken?
Have a look at this, please:

Sarah, the photo editor at Omnibus, asked me if I knew when or where this photo was taken. The caption included with the photo only says, Bono on stage, cutting up an American flag and throwing it back into audience.
First, that’s a white flag, not an American flag. Other than that, the main question is … when and where was this taken?
I gave Sarah a guess, but thought I’d turn to you, the ultra-smart U2 fans following this blog, to see if you know more about the photo than I do. I’m guessing you do.
Let me know in the comments, please!
