Kings of Leon cancel rest of US tour dates

NASHVILLE, Tenn. -- Kings of Leon singer Caleb Followill is suffering from vocal problems and exhaustion, forcing the band to cancel its U.S. tour.

Promoter Live Nation announced the cancellation in a news release Monday, three days after Followill left the stage mid-show in Dallas due to the heat on Friday.

Followill's exit led to vows to replay the show by his brothers, Nathan and Jared, and cousin Matthew on Twitter. But Jared Followill also acknowledged the band has "internal sicknesses & problems" that go beyond dehydration that must be addressed.

A statement says the Nashville, Tenn., band is "devastated, but in order to give their fans the shows they deserve, they need to take this break."

The band was scheduled to perform Sept. 3 in the Mandalay Bay Events Center. Tickets will be refunded at the point of purchase. Tickets purchased online or via phones will be automatically refunded.
