Heart stars Ann and Nancy Wilson have slammed U.S. presidential candidate John McCain for using their hit song Barracuda as his campaign's theme song without their prior permission.

Republican leader McCain chose the song as the theme track for his running mate Sarah Palin - whose high-school nickname was "Sarah Barracuda" because of her forceful style of playing basketball. However, the Wilsons are furious their song has been linked in with the McCain campaign trail, and are demanding the track is scrapped from further promotional duties.

Ann Wilson first became aware of the use of her track after watching Palin's speech on TV on Wednesday. According to TMZ.com, the pair has sent a 'cease and desist' letter to McCain and Palin's representatives.

In the letter, a representative for the duo says, "The Republican campaign did not ask for permission to use the song, nor would they have been granted that permission. We have asked the Republican campaign publicly not to use our music. We hope our wishes will be honored."
