Rondor Music has fired off a letter to Perry's label, Capitol Records, demanding Mike Love and Brian Wilson - who penned the 1965 classic "California Girls" - be given a writing credit on Perry's hit summer song, as well as royalties.
"Rondor Music has sent a letter to Capitol on behalf of Mike Love and Brian Wilson, saying Katy has cribbed one of the most famous lyrics in history, so Love and Wilson should be entitled to a writing credit and a portion of the royalties," the New York Post quoted a record industry source as telling Page Six.
The legendary line has been uttered by Snoop Dogg at the very end of Perry's track, which has sold more than 3 million copies, making it the anthem of the summer. Although sources told that Wilson and Love asked Rondor to take action, reps for both musicians claimed it was Rondor's idea.
Wilson's rep said, "Rondor owns the track and called Brian and Mike, saying they were going to complain. Brian likes Katy's record and doesn't know where the situation stands."
Love's rep said, "Mike and Brian wrote the song . . . but any legal action is up to Rondor." Rondor declined to comment.
