Four disappointed fans have launched a $1.8 million lawsuit against Creed because frontman Scott Stapp was allegedly incapable of getting through a single song:
"Creed is alleged to "have failed to substantially perform" on the stage.
Court papers claim Stapp was "so intoxicated" or "medicated" that he was "unable to sing a single Creed song".
He was said to have "left the stage on several occasions during songs for long periods of time, rolled around the floors in apparent pain or distress" and at one point "appeared to pass out".
Jeff Hanson, Creed's manager, was said in the suit to have issued a statement saying the group was sorry for its performance."
