On Sunday, Jimmy Buffett performed at a fundraiser for Florida governor candidate Alex Sink. The event raised $500,000 for Sink.

The set was short — just a few songs, including “Margaritaville” and “Volcano.” But the cash haul was big — about $500,000, according to Morgan.

“The best night ever,” Morgan said, adding that the highlight was when Buffett agreed to play his and his wife’s special song: “Come Monday.”
