Toby Keith, Eli Young Band + More Close Out Another Rockin’ Country Jam [Pictures]

Country Jam Colorado 2015 has officially come to an end, but it went out with the raising of many a red Solo cup! The festival wrapped after four busy days of great country music, with Mr. Toby Keith playing the grand finale.

Sunday (June 21)'s festivities kicked off in the heat of the afternoon with a very interactive set by Utah native Charley Jenkins. The rugged singer called the festival a "family reunion," since he saw a lot of familiar faces in the crowd. Chris Janson took the stage next and revealed how gracious he was to be standing on the stage. He thanked the crowd for helping him get to where he is, showered his family with affection and delivered the song fans waited in the heat to hear: "Buy Me a Boat."

Randy Rogers Band then brought a little bit of Texas to Grand Junction with their set, and even across borders, the crowd loved it. The fans were especially excited when the group sang the hit "Kiss Me in the Dark," and it became a singalong. Another great Texas band, the Eli Young Band, played immediate opening act for Keith, warming up the crowd with covers like David Lee Murphy's "Dust on the Bottle" along with their own hits in "Dust," "Crazy Girl" and "Drunk Last Night." Mike Eli made sure to express his thanks to the military men and women in attendance at Country Jam 2015, the ones that make it so they — and we — can get a little wild on a Sunday night in the mountains.

Keith finished off the night, and the 2015 festival, with a party. He brought out his microphone stand that held his personal Solo cup, but also giant versions. The singer performed hits from way back in his catalog, with his biggest Colorado fans singing along loud and proud.
