I don't think Edge is a full four inches taller than Bono. Two or maybe three, but not four. Based on the jillions of things I've read over the years (I'm so pathetic), my best guess is this: Bono 5'6", Larry 5'6" or possibly 5'7" (but not more), Edge 5'8" (at most 5'9") amd Adam 5'10". None of them is tall, and they have joked about this themselves. (Remember Edge dressing up as himself for Hallowe'en a few years back, and having someone say to him, "Wow, you really look like the Edge, only the real Edge is much taller!") I also remember a passage in the Flannagan book describing Anton Corbijn keeping an eye on his "tiny" band. I actually like the fact that they are small. I don't like to be towered over. It's great to be able to look someone in the eye (especially when those particular eyes are so blue, eh?)
