"It was about the mid-Eighties before I got all funky and into dance stuff. We didn't get rhythm until we went on the road with BB King. R&B was where we discovered rhythm and that wasn't until the late Eighties. While everyone was doing drugs during the summer of love in London, we were in Memphis hanging out with the Muscle Shoals brass section and getting into rhythm that way. I guess, it came together for us with Achtung Baby." - Bono, 1999
