This is one of four songs on Ride Me Back Home that Willie Nelson wrote with longtime producer and collaborator Buddy Cannon. In two of them, Nelson confronts death with a mix of humor and acceptance. On "Come on Time," he's outright daring the Grim Reaper to come and have a go if he thinks he's hard enough. Meanwhile, this song is about the realization that his time on earth is going to finish soon, whether he likes it or not.
The song is actually a Last Man Standing leftover. That album, released in April 2018, is made up entirely of Nelson and Cannon-written tunes.
Asked about his songwriting partnership with Willie Nelson, Buddy Cannon told Uncut magazine in 2019: "We've written maybe 35 to 40 songs together, all of them via text messaging. We've never sat down in a room with guitars. We bounce messages back and forth until we get a lyric we like, and then we get on the phone and talk about a melody or a groove, and that's usually when he'll tell me to go cut a track. But we really don't know what it's going to sound like until he sings it."
