I have a copy of "The Army Song Book", published in 1941. The flyleaf proudly announces:

__________________________________________________________
Army Song Book

Compiled by the Adjutant General's Office in collaboration with the Library of Congress and published by order of the Secretary of War.

This book is the property of the United States Government and its contents may be used only within the military services.

______________________________________________________
It has been rubber stamped in red: SPECIAL SERVICE OFFICE HQRS, THIRD ARMY.

Wonder if it bears any resemblance to what was actually being sung by troops at the time?!
