CHICAGO — A member of the band “Survivor” has sued Mike Huckabee’s presidential campaign for allegedly violating the copyright of the 1980s’ hit, “Eye of the Tiger.”

A lawsuit filed in Chicago federal court Wednesday says the Republican’s campaign played it at a Kentucky rally for a county clerk who refused to issue marriage licenses to same-sex couples. The song that featured in the movie “Rocky III” played as Kim Davis departed jail with the former Arkansas governor.

The suit says Frank M. Sullivan III is co-author of “Eye of the Tiger.” It says his suburban Chicago company, Rude Music, holds the copyright.
