Radio Margaritaville will broadcast Jimmy Buffett’s charity show tonight in San Francisco.

Buffett will take the stage at The Fillmore at 8 pm PT / 11 pm ET. Listen live on the web or on Sirius XM.

The show will benefit Jimmy’s charity Singing for Change, which offers competitive grants to progressive, community-based, nonprofit organizations that address the root causes of social and environmental problems.

Jimmy Buffett was in Orlando on Friday night to help Democratic incumbent senator Bill Nelson kick off a statewide campaign tour.

U.S. Sen. Bill Nelson kicked off a cross-state tour Friday with singer Jimmy Buffett at his side, starting an itinerary that will take him to at least 19 stops in the last weeks of a hard-fought campaign against Republican U.S. Rep. Connie Mack.

About 100 supporters swayed and snapped cell phone photos of Buffett as he sang acoustical versions of “It’s Five O’Clock Somewhere” and “Margaritaville” in a hangar at the Orlando-Sanford International Airport. Nelson and his wife, Grace, danced alongside him.

“Go support Bill Nelson and the Democrats because guess what? Florida matters,” said Buffett, who was dressed in shorts, flip flops and sunglasses.

Nelson said the tour underscored his commitment to visit as many places in Florida as he can, even Republican bastions like the retirement community, The Villages, northwest of Orlando
