Neurosis lead singer Scott Kelly returns for his fifth cameo with Mastodon, singing on this 7-minute album closer. Bassist Troy Sanders commented to Kerrang! magazine: "He's been on other albums of ours, but the part he does on this gives me absolute chills when I listen to it."
Mastodon drummer Brann Dailor told Exclaim! magazine that Scott Kelly picked the song. "He gravitated to that more," Dailor said. "He basically said, 'I love this track, I'm feeling it, I can kill this one.' So we said 'have at it, go kill it' and he did."
Mastodon described the song in the press release as focusing on "the fragility of responsibility."
In The Beatles "When I'm 64," Paul McCartney asks a woman if she'll still be there for him when he's 64. In 2006, he got his answer when shortly before his 64th birthday, he and Heather Mills separated.
