"The spirit of rock & roll is always about innovation and energy, fucking with the technology that was around. In the early days that were just this little printed circuits they overloaded and then you got distorted guitar and amplified instruments. It’s just a different kind of technology now, but I think it’s the same spirit. Our version of rock & roll is reflected in the song MOFO. That’s rock & roll."
- Bono, 1997

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.
