Oxford Bookworms Library 1 Piano Man + mp3

A woman finds a man on a beach. He is very cold, his clothes are wet, and he cannot speak. The woman phones for help, and an ambulance takes the man to hospital. In hospital they ask him questions, but he does not answer. He still cannot speak - or does not want to speak. Who is he? Where did he come from? And why do they call him the Piano Man?
