Kings of Leon cancelling several shows!

It is reported that Kings of Leon lead singer, Caleb Followill, bailed half way threw their show in Dallas, TX saying it was to hot and he need to "Vomit and drink a beer". When it was obvious that he was not going to return his band members took the mic to apologize that Caleb wasn't going to be finishing the show. 


Obviously, the band was not happy because before they left the stage they said "Blame Caleb not us". Also, reports say that the band has cancelled there show in Houston, TX tonight. I am sure there are a lot of angry fans out there. Is this the end of Kings of Leon?
