Kings of Leon Cancel Tour, including Camden Show

Last week, Kings of Leon singer Caleb Followill told a Dallas crowd that his voice was  "completely 100 percent gone." Then he said, "I'm gonna go back stage for a second, I'm gonna vomit, I'm gonna drink a beer and play three more songs."

The drinking and upchucking must have taken longer than anticipated, however, as Followill never came back out, and now the band of brothers has cancelled the rest of their tour, including a Aug. 12 date at the Susquehanna Bank Center in Camden.

The reason given for the cancellation was the lead singer's "vocal issues and exhaustion." But on Saturday Caleb's bass playing brother Jared suggested there was something more troubling going on, tweeting to fans that "there are internal sicknesses & problems that have needed to be addressed" and ""I know you guys aren't stupid. I can't lie. There are problems in our band bigger than not drinking enough Gatorade."

The KoL shows will not be rescheduled. The tour by the Southern arena-rock band, who won the record of the year Grammy in 2009 for "Use Somebody," will resume on Sept. 28 in Vancouver. Tickets will be refunded at point of purchase.
