Adams wrote this with Jim Vallance, who collaborated on most of his hits. On his website
, Vallance explains that this is a "relationship" song, but the second verse is about World War I. Said Vallance: "Adams and I are both interested in First World War history (Bryan's grandfather served with the British Army in WW1). As a result, lyrical references to that war occasionally appear in our songwriting. It's not always in context, and it doesn't always make sense, but there it is!"
