John Mayer Hospitalized for Emergency Appendectomy & Co., the band made up of several surviving Grateful Dead members and John Mayer, were forced to cancel Tuesday night’s show in New Orleans after Mayer was admitted to a Big Easy hospital for an emergency appendectomy. It’s not clear whether the band will play its final two shows of the year on Thursday and Friday in Florida; similarly, the status of Mayer’s co-headlining gigs with Dave Chappelle in Los Angeles on December 30 and 31 is unknown.
