Famed for his "beach bum" persona and music that epitomises a dreamy island lifestyle, Jimmy Buffett began his musical career in the 1960s. Released in 1977, his hit song Margaritaville – named after the popular cocktail – has been credited as one of the 'Songs of the Century' by the Recording Industry of America.
Buffett has created an empire built around the track's success, launching a string of restaurants, bars, hotels, and casinos, most of which are named after the hit single. These ventures are part of his company, Margaritaville Holdings, and he also owns Margaritaville Foods, which produces chips, guacamole, salsa, shrimp, and chicken. He also makes beer in partnership with giant brewers Anheuser-Busch. All in all, it's estimated by various sources that Buffett has a fortune somewhere in the region of $550 million (£399m).
