2018's Stagecoach Festival brought surprises — there were loads of special guests! Fans who caught Keith Urban's headlining set on Saturday night (April 28) also got Dwight Yoakam and Brothers Osborne on the stage.

Both Yoakam and Brothers Osborne had played the festival earlier in the day, and when Urban launched into a cover of Yoakam's "Fast as You," it quickly turned into an epic jam. TJ Osborne had the honor of kicking it off, with Urban and John Osborne trading guitar licks nearby. Then, Yoakam walked onto the stage.

Donning his signature cowboy hat and jean jacket, Yoakam's star power was apparent as soon as he took over the microphone. A mesmerizing guitar jam towards the end of the song had Yoakam spinning around and playing his guitar high in the air as Urban and John Osborne added to the musical interlude.

All three acts seemed to have a blast — as Yoakam left the stage Urban he could be seen thanking Urban for letting him his set.

Brothers Osborne were also in awe of the collaboration, sharing a photo of the three artists shredding together:

Also at Stagecoach 2018, "Walmart Boy" Mason Ramsey joined Florida Georgia Line onstage during their headlining set on Friday at the Empire Polo Club in Indio, Calif. FGL also brought out Jason Derulo during their performance.
