The boys of U2 are home. It’s Friday, 27 November, two weeks after the terrorist attacks in Paris. Bono, The Edge, Adam Clayton, and Larry Mullen Jr had been in Paris that terrible evening, rehearsing at the venue where they were scheduled to perform the following night. Instead, they had to be evacuated. This band has always been known for its political and social activism, and its songs’ messages against war and terrorism. Tonight, those themes feel particularly relevant.
