We'll Knock The Heligo-- Into Heligo-- Out Of Heligoland!

We'll Knock The Heligo—Into Heligo—Out Of Heligoland! is a World War I song written by John J. O'Brien and composed by Theodore Morse. The song was first published in 1917 by Leo Feist Inc., in New York, NY. The sheet music cover depicts a terrified Kaiser Wilhelm II standing on top of Heligoland while shells are bursting in his back and United States sailors with guns are rushing toward him.

The sheet music can be found at the Pritzker Military Museum & Library.
