"Ain't Back Yet" is Kenny's new single and also serves as the theme for his upcoming movie, Kenny Chesney: Summer in 3-D. "This Is Our Moment" was heard throughout the college football season as the theme for ESPN's college football coverage. Kenny notes that he decided to add the songs because he won't have a new studio album until the fall. "You want them when the moment is still fresh," he says. The two added tunes will be available on the digital reissue release of Greatest Hits II, March 2, and will also be stripped onto the physical CD copies of the album, also available around the same time.
