U2 recored this song in 1987 live of the floor at the Legendary Sun Studios. In attendance was the guy they the wrote the song specifically to duet with legendary BB King.
King and Bono certainly bonded over this song; King was amazed that Bono could write such mature lyrics at such a young age, and Bono was blown away by King’s vocal.
As Bono puts it “I gave it my absolute everything I had in that howl at the start of the song,” Bono said. “Then B.B. opened his mouth, and I felt like a girl.”
