Former Mayor Rudy Giuliani changed his opening tune to Van Halen's "Best of Both Worlds," which debuted on Thursday at a rally at the Embassy Suites in Boca Raton.

Giuliani used to make his entrance to a song from the 1993 movie Rudy, a sort of sweeping, regal song, said spokeswoman Maria Comella. This new one is a bit more hard core.

Giuliani started his speech off by asking about early voting: "How many people here have already voted?"

Nearly a third of the room raised their hands, some cheered and one man yelled, "Twice!"

To which Giuliani responded: "We're not Democrats here."

Despite his struggle in the polls, his event was packed with a few hundred South Floridians, who were quite animated in their support, often breaking into chants of, "Rudy, Rudy, Rudy."
