Tony Bennett, legendary singer of pop standards and jazz ballads, canceled a concert in Pennsylvania due to “mild flu virus,” his publicist said, according to the Associated Press. The 90-year-old performer was scheduled to take the stage at the Sands Bethlehem Event Center on Saturday night. On Friday, the venue announced the show was postponed. Bennett was advised not to travel or perform for the “next few days” according to the venue’s announcement, the AP reports.
