"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
Get On Your Boots is about Bono taking his family on vacation to France and witnessing warplanes flying overhead at the start of the Iraq War. The chant "let me in the sound" was developed late in the recording sessions and became a theme throughout parts of the album.
