The following cease-and-desist letter, supposedly written by Ann and Nancy Wilson of Heart to John McCain, has started doing the rounds. Warning: NSFW language!
Is it real? Well, the Wilsons did email out a statement asking the Republican campaign not to use their music, and in a phone interview, after the Republicans used their music anyway, Nancy Wilson said, "I feel completely f--ed over."
However, the article above seems to be satire. It comes from Seattle's The Stranger newspaper and ran as their "New Column" feature, which usually is a spoof piece. (Thanks, Big Gary!)
