Kings of Leon Just Cancelled Their Entire US Tour...

Can you get away with this sort of thing anymore? Will the fans forgive you - especially with money this tight, with so many other entertainment options?

After an on-stage meltdown in Dallas by frontman Caleb Followill on Friday, Kings of Leon have cancelled the remaining dates of their US tour, citing 'exhaustion' and 'vocal issues'. "The band is devastated, but in order to give their fans the shows they deserve, they need to take this break," a publicist for the group offered. "These guys do not stop and I think they are seriously exhausted."

The cancellation affects a total of 26 concerts, until the band resumes its aggressive touring schedule in Vancouver. That is the start of an international leg, one that apparently prevents make-up dates back in the states.

This is about a lot more than 'exhaustion,' and even brother Jared tweeted that "there are problems in our band bigger than not drinking enough Gatorade." In other words, this could be the beginning of a widening problem, whether that involves drugs, infighting, alcohol, or a combination thereof. "There are internal sicknesses & problems that have needed to be addressed."
