These seven organizations inspired many war songs. Below are some American sheet music covers from the First World War. American sheet music during World War I served many different purposes. Some of the song covers, such as “When Yankee Doodle learns to Parlez Vous Francais,” hint at prostitution and drinking among the American Expeditionary Force, activities the United War Work Campaign sought to curtail. The organizations, in turn, had their own sheet music that portrayed the gratitude soldiers felt towards the organizations, such as “The Red Triangle Man,” or offered a different example of womanhood, such as “Sweet Salvation Lassie.” Other sheet music covers listed below, such as “Just One Flag” and “We are All Americans,” encouraged nationalism and patriotism.
