Billy Joel, the renowned US singer, has been diagnosed with a brain disorder that has compelled him to cancel a planned tour and close his beloved motorcycle shop in New York. The shop, located on Long Island, housed his personal collection of dozens of vintage motorcycles and had been open for nearly 15 years, offering fans a free glimpse of his collection. Following the diagnosis, Joel plans to auction off his motorcycle collection. Additionally, the absence of Billy Joel has had a financial impact on MSG Entertainment, with the company's fiscal year profit falling by 74%.
