GRANGER SMITH

For his Sunday set, Smith performed a string of songs such as “You’re In It,” “Backroad Song” and covers of the Tom Petty classic “Free Fallin’” and Alabama’s “I’m in a Hurry (And Don’t Know Why.)” Smith also threw guitar picks into the crowd and took selfies with his fans.

But then, as quick as he had amped them up, Smith brought things to a quieter tone, grabbing a stool and taking it to the end of the stage. “I love this show and I love you guys for being here,” he told the crowd. He then gazed up into the sky, and started to sing the somber “Heaven Bound Balloons.”

At the end of the song, Granger quickly walked off stage, off to the side where he could be seen standing with someone who quickly put his arm around him.

“Chicago, you ready to take this to the next level?” Smith would later yell on stage. The rest of the show was quintessential, high-energy Smith, performing songs like “City Boy Stuck,” “Happens Like That,” and a surprise collaboration with Mitchell Tenpenny on “If the Boot Fits.” Smith’s alter-ego, Earl Dibbles Jr., even made an appearance for the set-ending “The Country Boy Song.”
