Written in 2009 while Kings of Leon were touring, the band unveiled this acoustic ballad on March 31, 2020 amid the coronavirus pandemic. With lyrics about being unable to meet up with loved ones, it fit in perfectly with people self-isolating during the lockdown.
The song was released as Kings of Leon first new music since their 2016 Walls album.
Regular Kings of Leon collaborator Casey McGrath directed the sparse, black-and-white video. Shot live in Nashville, it shows frontman Caleb Followill sitting on the side of a couch in an empty room. He croons the lyrics with his back to the camera while strumming his guitar.
"Kickstart My Heart" is about all the ways Motley Crue gets their blood flowing without drugs. It was inspired by their bass player Nikki Sixx, who claimed he had to be revived with a shot of adrenaline to the heart after an overdose.
Ronnie Dunn wrote "Boot Scootin' Boogie" before he teamed up with Kix Brooks to form Brooks & Dunn. It was originally recorded by the country group Asleep At The Wheel, but Brooks & Dunn did it themselves when it got its own line dance.
