A lone pianist touched the emotional core of Western sensibilities when he played John Lennon’s “Imagine†outside the Bataclan theatre in Paris, where concert-goers were murdered by Islamist gunmen last weekend. The pianist was reportedly watching a France v Germany soccer game when the attacks began. He said that he “just knew he had to do something.†It was his “duty†to pay tribute to the victims of the Paris attacks. So he drove 400 miles through the night from Konstanz, Germany to Paris.
