PITTSBURGH — Singer Jimmy Buffet wants a Pittsburgh bar named Margaritaville to quit using the name.

Buffett's lawyers sent the bar's owner a letter recently demanding it cease operating, saying the singer owns dozens of restaurants called Margaritaville.

Buffett released the song "Wasting Away Again In Margaritaville" in 1977.

Bar owner Rich Rizzo hired a lawyer and hopes to work things out, but he acknowledged Buffett's copyright could force a name change.
