This reminds me of the O. Henry short story, "The Ransom Of Red Chief."
Kidnapper Releases 10-Year-Old Who Won’t Stop Singing Gospel Song
A gospel song saved a 10-year-old Atlanta boy from his kidnapper. Willie Myrick said he was in his front yard and bent down to pick up money when somebody grabbed him and threw him in a car.
“He told me he didn’t want to hear a word from me,” Myrick said. That’s when Myrick began to sing a gospel song called “Every Praise.”
The kidnapper started cursing and repeatedly told Myrick to shut up, but he wouldn’t. He sang the song for about three hours until the kidnapper let him out of the car.
The little boy ran to a nearby home and asked the resident to call his guardian.
