“Where this song comes in was I was really, really sad, like the kind of sad …everyone’s there once in their lives, hopefully only once,” he told SiriusXM’s Buzz Brainard in a new radio interview on The Highway. “I was sad about everything. And this song idea came to mind, and it was like, ‘Never on the Day You Leave.’ I don’t know where it came from, but I just thought, all at once it came out full-cloth, and the song was written in 20 minutes.”

Though the words came quickly, there was one lyric in the song that really got to Mayer.
