At one point, we had 60 songs -- some with complete lyrics, some half complete -- that we had to narrow it down from.
It always amazes me when you read something like this about any of the great musical acts and how they just have tons and tons of content, sometimes full songs, that will never see the light of day.
Makes me want there to be a "U2 National Archive" someday where every single little thing would be available to listen to in one form or another of completion! That would be a nightmare for any creative person probably, letting people see all that unfinished work, but a real treat for me as a fan!
