Today is World Refugee Day, a good day to remember that there are many millions of refugees living in horrifying conditions in the world and in need of urgent action. Of course, for refugees, every day is refugee day.

Despite the desperation of their plight, many refugees remain hopeful, and this anthem called "No More Lines" has sprung up. It was recorded live on June 4, 2016 at the Eko Station Refugee Camp near Polykastro, Greece, with hundreds of refugees from many countries as well as relief workers.
