Hello, Rex (Beads).
One of my favorite symphonic pieces is
"Appalachian Spring", by USA composer
Aaron Copland (1900-1990).
It has a melody taken from a religious hymn,
known as the "Shakers' Hymn". It also has
other titles, including "The Lord of the Dance".
Have you searched for it? You might enjoy it.
Other melodies from popular tunes, converted
to religious tunes, include "What Child Is This?"
("Greensleeves", unknown composer, circa 1500?);
and "Going Home," also named "From the New World",
("Symphony #9"), by Czechoslovakian composer
Antonin Dvorak (1841-1904).
