Tim McGraw and Faith Hill fans are still waiting to hear the full version of the couple's new duet, "Keep Your Eyes on Me," but on Thursday (Jan. 26), Hill offered up a little something to tide listeners over: On Instagram, the country star shared the lyrics to the new tune.

According to the photo Hill shared -- which shows the lyrics to "Keep Your Eyes on Me" typed out on a piece of paper, along with some notes about certain lines -- some of the lyrics for the new song include "Ain't it just like a tear / To go and blur out everything / Ain't it just like glass / To fall and break so easily / Ain't it just like love / To leave a mark on the skin and underneath ..."

McGraw, meanwhile, shared a rough sketch outlining the melody to "Keep Your Eyes on Me" on his own Instagram account. He and Hill penned the song with Lori McKenna and Shane McAnally, specifically for the upcoming new movie The Shack; according to McGraw, the song was inspired by some of the film's dialogue.

“There’s a part where that line is spoken,” he explains, “and it was so powerful, and we took that and ran with it.”

The Shack tells the story of Mack Phillips (Sam Worthington)’s spiritual journey following a family tragedy; after Phillips begins questioning his beliefs and faces a crisis of faith, a mysterious letter leads him to an abandoned shack in the Oregon wilderness, where he meets a trio of strangers who help him make sense of what’s happened. McGraw plays the character Willie and acts as the movie's narrator; the film is set for release on March 3.

McGraw and Hill celebrated their 20th wedding anniversary in October of 2016; during the same week, the pair received stars on the Music City Walk of Fame and hosted a sold-out “surprise” concert at the Ryman Auditorium to announce a co-headlining tour, which will begin in April. In early January, it was announced that they will be the subjects of a Country Music Hall of Fame exhibit beginning in November.
