Sept. 22 (UPI) -- Country music artist Eric Church performed and discussed his song "Johnny" on The Tonight Show starring Jimmy Fallon Sunday.

Church, 38, appeared on the stage in a leather jacket and dark sunglasses, and was joined by a chorus of back-up singers as the track continued.

"Johnny, oh Johnny, where did you go? The devil's broke out of Georgia and he's feasting on my soul," he sang.

"The hardest thing I've ever done in my life -- we had a school shooting in Nashville at the Covenant School, and dropping my -- I have two boys, 13 and 10 -- and the day after that school shooting, dropping them off at school was the hardest thing I've ever done," he told Fallon, explaining the meaning behind the song.
