CREED are being sued by fans who claim the quality of the band’s performance cheated them out of a real concert.

Four fans, Philip and Linda Berenz and Wendy and Chad Costino — claim singer Scott Stapp was so “intoxicated and/or medicated that he was unable to sing the lyrics of a single Creed song” during a gig at the at Illinois Allstate Arena

Each are looking to get back the $56.75 each they spent on tickets, service charges and parking fees. The suit alleges: “Stapp left the stage on several occasions during songs for long periods of time, rolled around on the floor of the stage in apparent pain or distress and appeared to pass out while onstage during the performance,” Rolling Stone reports.

Shortly after the show, the band apologised for its quality. An email to fans said: “We apologise if you don’t feel that the show was up to the very high standards set by our previous shows. We also understand and appreciate the fact that there has been much concern about Scott’s health. [He] is taking a much needed break at home in Orlando. For now, we hope that you can take some solace in the fact that you definitely experienced the most unique of all Creed shows.”
