John Mellencamp vs. John McCain, George W. Bush and Ronald Reagan
When: 2008, 2000 and 1984
Songs: "Our Country," "Pink Houses"; "R.O.C.K. in the U.S.A."; "Pink Houses"
Controversy: McCain used the tunes at rallies to underscore his "Country First" message. Mellencamp – who has called himself "as left-wing as you can get" and performed at a John Edwards rally during the 2008 Democratic primaries – asked that the presidential hopeful cease and desist. The rocker also asked Bush to stop using "R.O.C.K. in the U.S.A." in 2000, and told Salon that he discouraged Reagan from using "Pink Houses" as his campaign song in 1984 when reps reached out.
Result: Four days after Mellencamp's request was made, McCain's campaign announced that it would no longer play either "Our Country" or "Pink Houses" at events.
