@pbsnews: Billy Joel announced Friday that he is canceling all of his upcoming concerts after being diagnosed with a brain disorder known as normal pressure hydrocephalus, or NPH. The condition involves a buildup of spinal fluid in the brain and leads to problems with hearing, vision and balance. The 76-year-old had concert dates scheduled through July 2026 in North America and England. Those who had tickets will get an automatic refund. In a statement posted on social media, Joel said he was "sincerely sorry to disappoint" his fans. #pbsnewshour #newshour #pbsnews #billyjoel #health #news
