"Margaritaville" a 1977 song by American   
    popular music singer-songwriter Jimmy Buffett  wrote it  
in Fort Myers, Florida after touring Texas with his group, the
Coral Reefer Band. It reached #8 on Billboard Hot 100 chart,
topped the Easy Listening (Adult Contemporary) chart at #1,
   Named for a cocktail, the margarita, and with lyrics
reflecting a laid-back lifestyle in a tropical climate.
   "Margaritaville" has come to define Buffett's music and
careerThe song is a narrative overview of the singer's life
for the previous season. He sings about laid-back living in a
drunken haze in a beach community. "Margaritaville" is the
mental state in which he exists during this period, induced—
presumably—from the perpetual imbibing of margaritas.
This is best illustrated in the last verse, when the singer
goes for a walk, cuts his heel and returns home to ease his
pain with the eponymous alcoholic beverage. The singer
says that some friends surmise that he is reeling from a    
failed romance.
