• The bulk of No Turning Back was produced by Ed Cash (Chris Tomlin, Kari Jobe, Steven Curtis Chapman). Cash also wrote this poignant ballad. "I have never recorded a song on one of my records – aside from a Christmas record – that I didn't write," said Brandon Heath. "But Ed wrote that song for high school kids. He wrote it to sing at camp and I thought it captured where I was at the time, as a teenager. So I thought, 'This has to go on the record!'"
  
  "Ed is really close to that song and he tried to record it a few other times and it just wasn't panning out. So I just put my vocal on it and owned it.," he added. "And Ed loved it!"
• The song reflects how Heath felt as a teenager. "You start to really see the brokenness of the world, and you're not as protected as you were as a kid," he said. "All of a sudden you feel alone in a turbulent world and you're trying to figure everything out as best you can. So many teenagers are desperately looking for something. Some of us along the way find God and realize that He's made us and He understands what we need."
• SOS is the international Morse code distress signal (three dots, three dashes, and three dots, all run together without letter spacing). It became the worldwide standard under the second International Radiotelegraphic Convention, which became effective on July 1, 1908.

  In 1917 San Francisco aluminium pot salesman Ed Cox, invented a pre-soaped pad with which to clean pots. As a way of introducing himself to potential new customers, Cox made the soap incrusted steel-wool pads as a calling card. These pads quickly became more popular than his pots and pans, so he gave up selling pots and concentrated on manufacturing the cleaning product. They still did not have a name until his wife came up with a solution - she had called them S.O.S pads in her kitchen, meaning "Save Our Saucepans."
  
  S.O.S. by ABBA is the only Top 20 hits in history in which the title of the song and the name of the artist are both palindromes - they spell the same thing forward and backward.
