What is the importance of post-war Britain in the memoir, Who I Am?

Following World War II, British people began to rebuild their lives after the terrors of air raids, rationing, loved ones' deaths, and constant fear. Pete remembers it as a time of optimism, but also a slightly selfish time in which people focused on their own happiness and tried to repress or deny anything bad. The older generation did not want to face the mistakes of the past, but the younger generation wanted to deal with these and then look ahead to the future. The working classes had more freedom and hope than ever before, as they could now look for opportunities beyond what their parents had always done. The music at this time began to express the anger, determination, hope and battle for freedom that the youth were experiencing.
