Classic '80s band Katrina And The Waves have threatened legal action against U.S. presidential candidate Michele Bachmann for playing their music on her campaign trail.
The Minnesota congresswoman has upset the pop stars after using their 1985 hit Walking on Sunshine as her anthem at a rally in South Carolina on Tuesday (28Jun11).
A statement on the group's official website reads: "Katrina & The Waves would like it to be known that they do not endorse the use of Walking On Sunshine by Michele Bachmann and have instructed their lawyers accordingly."
Frontwoman Katrina Leskanich admits she wants to ban the Republican from using the upbeat track because she doesn't approve of her politics.
In a statement to Rolling Stone magazine, the singer explains, "The song is used in commercials and movies as a vehicle for a feel good moment or empowerment but if I disagree with the policies, opinions or platforms for its use, I've no choice but to try and defend the song and prevent its misuse. Music can be both powerful and moving and sometimes even a little dangerous."
It's not the first time Bachmann has been taken to task for her song choices - rocker Tom Petty issued a cease and desist letter after she picked his track American Girl as her theme tune.
Perry appeared on James Corden's 'The Late Late Show' on Monday and addressed her long-standing rivalry with Swift.
