Billy Joel gave a health update during a call-in with fans on his SiriusXM channel this week, noting that he’s doing well after revealing earlier in September that he’d undergone brain surgery to relieve some of the symptoms of normal pressure hydrocephalus, a disorder he was diagnosed with in 2025.
