Thanks for the pictures, narratives, and songs you post there, Kathy. The song I posted ("Over There") was written for WWI, but was actually popular in both World Wars. My Dad went into Normandy to fight several weeks after the D-Day invasion with the 6th Armored Division, and, later, when we were growing up, we would occasionally hear him singing that song.
Here's another version of that song. (See the note that the poster of this youtube video included with the song, which says "'Over There' is a 1917 song written by George M. Cohan that was popular with the United States military and public during both world wars. It is a patriotic song designed to galvanize American young men to enlist and fight the 'Hun'. The song is best remembered for a line in its chorus: 'The Yanks are coming.'")
Another version of that song:
"Over There".
