While the abrupt cancellation frustrated and angered concertgoers, John released a statement on Twitter saying he was “sincerely sorry” for the shutdown.

"We are sincerely sorry to everyone due to attend the shows in Orlando last night and Tampa tonight," the statement began. "Elton has been on a course of antibiotics to combat an ear infection and it was expected that these would clear the infection in time to play the Orlando show."

The statement continued, "Elton and his band play 100% live and with impaired hearing and ear pain he wouldn't have been able to deliver the performance his fans deserve. He will take a couple of days rest to allow the infection to clear up and both will be rescheduled as soon as possible."
