I folk process stuff all the time.

For example, I just learned the original tune for "Peace in the Valley." I changed "I'm tired and weary" to "I'm weary and tired," because it fits the music better. I changed "no sorrow, no sadness, no trouble" to put the nouns in alphabetical order. That prevents a little glitch where otherwise I stop to think whether sorrow comes first or sadness.

I've shifted the verses of "She Walked through the Fair" to make a sensible story.

I'm sure other people do stuff like this all the time. That's folk process.
