What singer has Alzheimer's disease?
Could you please elaborate on the statement "What singer has Alzheimer's disease?" It's an intriguing question, but there are many singers in the world, and I'm not immediately aware of any specific individual who has publicly disclosed a diagnosis of Alzheimer's disease. Are you referring to a recent news story or a well-known figure in the music industry? If so, could you provide some context or additional information to help narrow down the possible answer? It would be great if we could have a more focused discussion based on accurate and up-to-date information.
