Buffett passed away aged 76, at his home in Sag Harbor, New York due to complications from merkel-cell carcinoma, a rare and aggressive form of skin cancer. The Margaritaville musician rose to fame in the 1970s with his laid-back country rock and counted a number of music megastars as pals. Elton remembered Buffett on his Instagram Story page, writing: "Jimmy Buffett was a unique and treasured entertainer. His fans adored him and he never let them down. This is the saddest of news. A lovely man gone way too soon..."
