Rough weather marred the Firefly Music Festival in Delaware over the weekend to the point that the site had to be evacuated on Saturday. Kings of Leon were forced to cancel their set that day, so during the Killers' performance on Sunday, the Vegas outfit covered Kings of Leon's "The Bucket" and "Use Somebody." Check out fan-shot footage of The Killers performing "The Bucket" below.

Before starting their set, the Killers frontman Brandon Flowers addressed the crowd, "I heard you had a little trouble yesterday. We're trying to make up for it the best we can." The band's set at Firefly was their first live performance since the Tennent's Vital festival in Northern Ireland in August 2014.

The Killers have been on hiatus since then, while Flowers has been promoting his sophomore solo album, The Desired Effect. He recently spoke about the band's future, saying, "“Once [the Killers] all get on the same page, it’ll work." The band's only scheduled upcoming performance is an appearance at Kaaboo 2015 in San Diego, Calif. on Sept. 18, 2015.
