"Working with B.B. King is a mixed blessing because he's the only guy I know that when he moves back from the microphone his voice gets louder. I feel like a little girl when I'm singing with him."
- Bono, 1989
The song 'Numb' is about how The Edge felt when he split up with his wife. He felt like he couldn't do anything, he was useless. He felt numb.
