Kenny Chesney and Jason Aldean not only shared the bill at the Rose Bowl in Pasadena, Calif., on Saturday night (July 25) -- they also shared the stage. The two singers kept the crowd on their feet during Chesney's encore with a rendition of "She Thinks My Tractor's Sexy."

The country hitmakers co-headlined the concert, and their collaborations that evening didn't stop with the 1999 single from Chesney, which you can watch above. They also performed Aldean's "The Only Way I Know," John Mellencamp's "Hurts So Good" and Bryan Adams' "Summer of '69."

The show, which drew celebrity guests including Reese Witherspoon, Vince Vaughn, Ashton Kutcher and Mila Kunis, was a night that Chesney says he will never forget.

“Those folks had had a long day in all that heat, but, man, they were so ready for us ... ready to hear the music, to sing along, to make every single song matter,” he shares. “When I dropped out during "Anything But Mine," they sang so clear and so true, you could’ve made a record out of it -- and for me, they made a memory that will last a lifetime. To play a place where football means so much, especially to an audience that live, I’ll never forget it.”

As Chesney notes, playing the Rose Bowl, with its rich sports history, was a dream come true.

"You know when you wake up and you see that sign, you’re on hallowed ground,” the "Save It for a Rainy Day" singer says. “I’ve seen so many games played there, so much history -- and I understand the heart it took from every athlete who’s ever come out of those tunnels. To stand on that stage, I knew I wanted to try to honor all those folks who’ve come before us.”

Chesney's 2015 The Big Revival Tour heads to Mississippi and Arkansas this weekend, with Jake Owen and Chase Rice serving as his opening acts. Aldean will join Chesney once again at his show at Arrowhead Stadium in Kansas City, Mo., on Aug. 1, as well as at his show at Sports Authority Field at Mile High in Denver, Colo., on Aug. 8. A list of all of Chesney's upcoming concerts, as well as ticketing information, is available on his website.
