Unfortunately the photo of soldiers listening to records on that page has the wrong caption. The caption shown with the photo actually matches the poster shown further down the page ("Music Inspires..." which can be found in the National Archives Catalog: https://catalog.archives.gov/id/515036 ). You may want to contact the NEH to see if they can locate the correct source of the photo.

Good luck with your research!
Thank you very much Darren. I will ask the NEH. (Google translation ...)
I will try to use it in Japanese TV broadcasting.
