Watch : Barry Manilow Cancels Concert Minutes Before Showtime Due to “Unforeseen Circumstances”Fans can’t smile without Barry Manilow. “Due to unforeseen circumstances,” Manilow wrote on X, “tonight’s show in Lexington has been rescheduled.” Manilow did not share additional insight into the schedule change.

Getting to that point, however, had taken its toll; Manilow had to have part of his left lung removed and endured seven days in the ICU.
