Creed Fans Sue Creed

Fans of the band Creed (muhahaha) are bring a class-action suit against the band for failing to “substantially perform” when the lead singer “was so intoxicated and/or medicated that he was unable to sing the lyrics of a single Creed song.”
This is one of those cases that sounds frivolous to people reading the articles (suing a band because they didn’t like the concert), but actually makes a lot of sense (in my opinion). Certainly, a duty to perform was created when the tickets were sold. Depending on what that duty was (would have to do a little research and analyze the specific facts), it’s conceivable if not probable that Creed breached their duty by failing to perform. I can’t seem to find a copy of the full complaint, but The Smoking Gun has the Statement of Facts section.
