The Jun 19, 1950 isue of LIFE has an article titled "Gunfire Lays Low One More Shelton"
with many photos, of course, including one of the recording -- and quotes these lines:

He left his dear old mother in sorrow there alone,
Living down near Merriam in her little country home.
May the angels hover over her for she hasn't long to stay,
And I hope she meets her darling in a better world some day.

as well as the third and fourth lines of the fourth stanza
and states "© 1948 by Earl Shelton and Fred Henson."
