Jimmy Buffett’s daughter reveals father’s last days in cancer battle: ‘Despite the pain, he smiled every day’

Jimmy Buffett’s daughter, Sarah "Delaney" Buffett, shared an emotional tribute to her late father after his sudden death. 

The legendary singer had been "fighting Merkel Cell Skin Cancer for four years," according to an official obituary for the star posted to his website. The "Margaritaville" icon died on Sept. 1 at his home in Sag Harbor, Long Island. He was 76 years old.

"I knew my dad my whole life but in his final days, I saw who he was: a man whose spirit could not be broken," Delaney began to share on Instagram.

"Despite the pain, he smiled everyday. He was kind when he had every excuse not to be. He told us not to be sad or scared, but to keep the party going. And as much as I'd like to use that as an excuse to drink myself into oblivion worthy of his literary heroes, I know it’s not what he meant," she continued. 

"My dad was the joy he sang about. He was the hardest working person I've ever seen. He was a great man and an even better dad to my brother, sister and me. He was generous with his friends and strangers alike. He had a deep admiration for the people he worked with, and he never took himself too seriously, which is probably what I loved most about him," Delaney, 31, said in part. 

Buffett’s daughter noted that her father adored his fans tremendously and was thankful to share the stage with his band while touring.

She went on to say how much Buffett expressed gratitude toward the hospital workers who took care of him leading up to his death and appreciated the unconditional support from his loved ones. 

"And finally, to my dad, thank you," she concluded. "You turned nothing into something and gave me everything. I will never be able to repay you or my mom for my beautiful life. I will love you forever, and I will always keep the party going (responsibly, of course)."

Buffett is survived by his wife of 46 years, Jane Slagsvol, and their three children, Savannah, Delaney and Cameron.
