There's a degree of irony in John McCain - a man who has helped the current administration dance to the whim of the copyright industries - choosing to pointedly ignore a cease-and-desist letter. The Wilson sisters from Heart made it clear they didn't want him using their music:
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."
So what came parping out of the speakers once McCain had got to the end of his "I'm not my own man" speech?
Copyright law is for other people. John McCain is a scofflaw.
