The ’70s rock band Heart has asked Sarah Palin to stop using “Barracuda” as her unofficial campaign song. “The Republican campaign did not ask for permission to use the song, nor would they have been granted permission,” said sisters Ann and Nancy Wilson. Van Halen released a similar statement about the campaign’s use of its song “Right Now,” even though Palin gave her son Trig the middle name Van in tribute to the rock group.
