MYRTLE BEACH, S.C.—Maybe Tom Petty’s cease-and-desist letter hasn’t arrived yet.

The singer was reportedly nonplussed that Michele Bachmann played his “American Girl” classic when she officially kicked off her presidential campaign in Iowa Monday.

Yet the song blasted over the loudspeakers again immediately following Bachmann's Tuesday night speech in South Carolina.

After playing for exactly 29 seconds, it abruptly stopped.

There was just enough time for the lyrics: “Yeah, she was an American girl – raised on promises.”

Then “Walking on Sunshine” came on in its place.

We’ll have to check if Katrina and The Waves have anything to say about this.
