While working on a Russian cruise ship, Guy Hobbs composed a song entitled “Natasha” that was inspired by a brief love affair he had with a Russian waitress. Hobbs tried to publish his song, but was unsuccessful. A few years later, Elton John and Bernie Taupin released a song entitled “Nikita” through a publishing company to which Hobbs had sent a copy of “Natasha.” Believing that “Nikita” was based upon “Natasha,” Hobbs eventually demanded compensation from John and Taupin, and ultimately filed suit asserting a copyright infringement claim and two related state law claims. The defendants moved to dismiss Hobbs’s complaint for failure to state a claim, and the district court granted the defendants’ motion. Hobbs appeals. We affirm.
