while U2 performs "One," fans will be able to send an SMS message via cellphone
in support of the ONE Campaign. The names of fans who sign this virtual petition
will appear on the video screen as U2 plays, and those fans will later be
invited to formally join the ONE Campaign.
Don't get me wrong. The campaign is a very important one. But surely it could be done like before the gig, have a video announcement from Bono telling you what todo, then have names on the screen durring the song. I don't really wannt to hear 15,000 mobile phones bleeping away, whilst the band are performing One. I hate mobile phones going off at gigs full stop. So to have the band encourage people to use the phone durring the gig surprises me.
