"It's a song about uncertainty. We talked a lot about uncertainty when we were making the record. Musically, uncertainty is the antidote to complacency. As far as the song was concerned, all the ad slogans were the real breakthrough for me. My favorite line is 'We're mild and green."
-The Edge on Zooropa
U2 changed many of the tracks' names of No Line On The Horizon during recording, retitling "French Disco" to "Magnificent" and "Crazy Tonight" to "I'll Go Crazy If I Don't Go Crazy Tonight". "Chromium Chords" became "Tripoli", and finally "Fez – Being Born".
