I recently listened to Nick Lowe’s song (What’s so funny ‘bout) peace, love and understanding? It had a particular resonance given the constant news of conflict, tension and strife across the world. The current outlook can feel quite bleak – as the first line of the song asks – “As I walk through this wicked world searching for light in the darkness of insanity, I ask myself is all hope gone? Is there only pain, hatred and misery?”
