'Miss Sarajevo' has become one of  the highlights of the 2010 show. Bill Carter has the story behind it.

Novelist Salman Rushdie was in hiding for fear of his life for many years. Then he showed up onstage with U2. Then he wrote a song with them. In this latest highlight from our archives he recalls how it all came about.

'Once the music began, no one cared about last names, nations, or religion. All they cared about was the music. The simple celebration of music became a celebration of the end of the war.' A week ahead of U2's Zagreb shows, Bill Carter remembers what it was like when U2 played Sarajevo in 1997... and how a city under siege had become a defining image of the ZOO TV Tour.

This weekend U2 return to Berlin, the city where they recorded Achtung Baby. Here's what it was like in 1990.
