Possibly the most outstanding example for the subject of this thread is "This Land is Your Land," which Woody Guthrie wrote and set to this early-gospel tune:

O my loving brother, when the world's on fire,
Don't you want God's bosom to be your pillow
O hide me over in the rock of ages-
Rock of ages, cleft for me!

Woody of course used hymn-tunes for many of his songs. When questioned about this, once, he said, "Well if you're gonna steal, steal from the best!"
