An announced appearance by singer-songwriter Jimmy Buffett guarantees thousands more will make their way to the free concert Saturday at The LandShark Beach in front of Resorts Casino Hotel in Atlantic City.

Buffett, whose biggest hit was the top-20 pop song "Margaritaville" in 1977, makes a special guest appearance at 4 p.m. during the set of Mac McAnally, who has long been a partner of Buffett as a songwriter, musician and producer. McAnally was the Country Music Association's Musician of the Year for five years straight.

The live performances start at 1 p.m. with adult pop singer Andy Grammer and conclude with 1990s hitmakers Wilson Phillips, whose headlining set begins at 7 p.m.

The free beach concert celebrates the launch of Jimmy Buffett's Margaritaville at Resorts. The $35 million Margaritaville-themed casino, dining and entertainment complex opened with a Memorial Day ribbon-cutting in front of Gov. Chris Christie and invited guests.

The Buffett-backed Margaritaville project was built at Resorts with the goal of attracting visitors to the city's oldest casino, which opened in 1978.

The beach concert is free and people can bring normal beach paraphernalia, such as chairs and blankets. There will be some concessions. Picnic baskets will be allowed.

Resorts offers valet and self-parking. Surface and garage parking will be available for self-parking. Parking will be $20 for valet and self parking. Other options include the Boardwalk Hall parking garage, 2301 Boardwalk, which will be open from 8 a.m. to 10 p.m. The charge will be $10. The Wave Parking Garage at Mississippi and Fairmount avenues is open 24 hours. Call 609-428-6014 for pricing. There is parking at neighboring private lots and street parking with meters.
