When life hands them lemons, the Brothers Osborne certainly know how to make lemonade: The duo was supposed to play at Hanford, Calif.'s Hanford Fox Theatre on Saturday night (Dec. 10), but the venue's roof started to crumble shortly before they were set to take the stage -- so, they played atop their tour bus, outside, instead.

"HANFORD! Ceiling caved in (again). Show in venue is canceled," the Brothers Osborne wrote on Instagram on Saturday night. "Be at our bus in 20 minutes."

John and TJ Osborne broadcast their 30-minute set, which literally took place on the roof of their tour bus, stationed outside the venue, on Facebook Live; readers can press play above to watch the brothers and their band run through "21 Summer," "Rum," "Stay a Little Longer" and more. Lucie Silvas, who is opening shows on the Brothers Osborne's current Dirt Rich Tour (and is John Osborne's wife) joined them for "Ain't My Fault."

Per the Visalia Times-Delta, the roof collapse inside the Fox Theatre occurred about five minutes before Saturday's show was scheduled to begin; no injuries were reported, but concertgoers were inside the venue when the incident took place.

Brothers Osborne dealt with a similar issue during their Nov. 27 concert at Boise, Idaho's Egyptian Theatre: Their set was cut short when pieces of the roof began falling onto the stage.

A list of all of the Osbornes’ upcoming shows is available on their website.
