Universal Music Group's Thursday afternoon (Feb. 26) showcase at the 2015 Country Radio Seminar was the place to be if you wanted to hear new music from some big country names -- including Eric Church.

The country superstar had showcase attendees wiping away tears, according to The Tennessean, after he played an unreleased song, inspired by his grandfather's diagnosis with Alzheimer's disease. Church was just 10 years old at the time.

"The hardest thing was to have a relationship when that person doesn't remember you," Church said (quote via People). Press play on the Instagram video above to hear a snippet of the song, the lyrics for which include the sweet sentiment that "He doesn't have to know me 'cause I know who he is."

Church is not yet sure if the song will appear on an upcoming album.

"It may never be recorded," he told the crowd. "We'll see how it goes."

It's unclear if this song is about the same grandfather with whom Church shares his nickname, "Chief." His maternal grandfather, Rusty, earned the same nickname as chief of police in Granite Falls, N.C.

"I thought it was interesting that we ended up with the same nickname, multi-generationally,” Church says. “And when it came to the title of the album, not only did it pay tribute to what’s happening on the road and what was was happening every night, but it also paid tribute to my grandfather … He was chief, I think, for 35 years.”

The "Like a Wrecking Ball" singer admitted during his stage time that he was tired, thanks to his brand-new son, Tennessee Hawkins Church, who was born on Feb. 15. Church also duetted with Keith Urban -- who had a new song to play as well -- on their new single “Raise ‘Em Up” during the showcase.
