GUEST# - the link you posted was the same one I provided in the OP.

It was not composed by Cal Bagby (Lou Gottlieb). The Limeliters/Gottlieb sometimes took credit for songs they did not write, but only slightly adapted.

In the film I mentioned, it is heard (very briefly) toward the end of the film, sung IIRC by some soldiers in the rail station. It is heard so briefly that I doubt it would be listed on any sort of soundtrack. But I confess it's been a number of years since I saw the film; both the short and long version are available on YouTube, if anyone's interested.
