 NEW YORK Republican presidential candidate Newt Gingrich faces a lawsuit over his use of "Eye of the Tiger," the theme song to the movie "Rocky III," court documents show. 
 
 The claim for copyright infringement, lodged on Monday by Rude Music Inc in an Illinois federal court, relates to Gingrich's use of the song at his political rallies. 
 
 Rude Music Inc is owned by Frank Sullivan, who co-wrote the Grammy-award winning song. In addition to Gingrich, the complaint names his campaign, Newt 2012 Inc, and the American Conservative Union, an advocacy organization, as defendants. 
 
 The complaint states that the violation it alleges is intentional since Gingrich is "sophisticated and knowledgeable" concerning copyright laws. Rude Music Inc has requested the court to order an end to unauthorized use of the song by the defendants, and to award Rude Music Inc damages. 
 
 A Gingrich campaign spokesman could not immediately be reached for comment. 
 
 The case is Rude Music Inc v Newt 2012 et al, U.S. District Court, Northern District of Illinois, no. 1:12-cv-00640.

– Newt Gingrich is going to have to start playing a different song as he battles his rivals, says Survivor guitarist Frankie Sullivan. The rocker is suing Gingrich over his use of "Eye of the Tiger" at campaign rallies, Reuters reports. Sullivan co-wrote the 1982 hit, best known as the theme song to Rocky III. A lawsuit filed by Sullivan's music company seeks damages and an injunction to stop Gingrich from using the song. "This has nothing to do with politics. This is a copyright issue," Sullivan's lawyer tells the Chicago Tribune. "We've tried to deal with them for months, and they've been trying to ignore it." The suit is far from the first copyright kerfuffle on the campaign trail. Tom Petty objected to Michele Bachmann's use of "American Girl" and, in 2008, Boston's founding member was outraged by Mike Huckabee's use of "More Than a Feeling."
