I read about that earlier. I have some margarita mix handy and some very good tequila. The Margaritaville song is so well known, that I've been able to cover it (it's not especially difficult, after all) for decades and across audiences of all ages.
The song has some of my favorite lyrics of all times...
"Some people claim that there's a woman to blame,
but I know it's my own d*mn fault."
Of course, I always get a kick out of "I blew out my flip flop. Stepped on a pop top. Cut my heel had to cruise on back home." It's lyrical genius in such a deceptively simple song. It describes a scene so vividly that there's no need for interpretation.
Edit to add:
For a LONG TIME my go-to drink was "margarita, no salt, cherries and not a lime".
