Tell us about the time you met the band, did you get the chance to ask or tell them something?
This one i'm not sure of. Though i wish i had, I have never in fact met U2 more than anyone else who has just been to a couple concerts. If i claimed i have in the past i was either:
a. shamelessly lying
b. misunderstood
or
c. under the influence of something that had given me the impression i have met the band
However, if i met them in real life i wouldn't really have much of anything to say. I would likely just thank them for making music which i have enjoyed so immensely and tell them to stick with it until they can't anymore.
