Welcome to the Everything is a Primary Source Podcast, where we use popular culture to learn about history. It was this week in 1917 that the United States entered World War I, so what better time than now to dissect the song that is forever attached to America’s involvement in the Great War, George M. Cohan's "Over There."

Everything is a Primary Source is building a digital archive, and you can get involved. Perhaps you would like to add to this conversation, or start a new one about history through pop culture.
