Babb wrote the lyrics of "One Heart" to comfort his wife, as her mother had only a few days left before her death.

The band expanded it into a non-acoustic version featuring all members, with Babb adding "the middle break with the solos and the very Gentle Giant-y part".

The piano break in the middle of the song is based around the guitar intro of "Dear Daddy".

The first day Babb started to work on the song, both his studio and home in Tennessee were slammed by a tornado.

All lyrics are written by Steve Babb, Fred Schendel and Jon Davison; all music is composed by Babb, Schendel, Davison and Alan ShikohGlass Hammer Additional musicians Production
