Ann and Nancy Wilson are hoping the Republicans change their tune—and aren't planning on waiting until November to find out.

The sisterly duo known as Heart sent a cease-and-desist notice to the McCain-Palin campaign Thursday afternoon after their hit "Barracuda" was used—twice—without permission as the official rallying cry for the vice presidential candidate after her nomination acceptance speech at the Republican National Convention.

The song was chosen as a would-be cute tie-in to Alaska Gov. Sarah Palin's past—"Barracuda" was her high school nickname.

Only problem, campaign officials failed to ask either the group, Universal Music Publishing or Sony BMG whether the song was fair game to use. It wasn't.
