The singer is suffering from “acute upper respiratory infection and laryngitis” and has been feeling under the weather for several days, said Max Loubiere, his tour manager.

Monday (March 11) night’s concert at the Ice Palace was scheduled as part of a national tour featuring the two artists.

Arena officials said the concert will be rescheduled, but no date was released. Ticketholders were advised to keep their tickets.

“We’re trying to see what the schedule is, what Elton’s schedule is,” Loubiere told the St. Petersburg Times. “We’ll just have to wait and see.”

Joel’s doctor advised against performing Saturday (March 9) night, but the artist did so anyway, singing to a sold-out, 3 ½-hour concert, Loubiere said.

Joel, 52, and John, 53, are scheduled to perform Friday (March 15) night at New York’s Madison Square Garden.
