I suspect that people will be playing Jimmy Buffett in fifty years, but they won't be playing "Margaritaville." Instead, they'll be playing "Death of an Unpopular Poet" and "He Went to Paris."
I don't know those, but I'm not a full and complete Parrothead and am separated from all my Buffett CDs - 20 or 30 or so - all oldies. I will look them up.
No matter where you go in the Caribbean, a deserted island with no other inhabitants, or a ship full of tourists, Buffett will be playing 24/7.
