Jimmy Buffett was an author, song-writer, singer, and environmentalist. His persona was formed with his first song, “A White Sport Coat and a Pink Crustacean.” His biggest hit came in 1977 with “Margaritaville.” But his most valuable album is the 1970 release, “Down to Earth.” Issued on Barnaby Records, a copy can sell for up to $200.00 today. A year earlier Audio Mobile Records issued the Jimmy Buffet 45, “Abandoned on Tuesday.” That single can now sell for $500.00.
