Frankie Sullivan and Jim Peterik
were Survivor's primary songwriters. When they wrote "Eye Of The Tiger," Stallone sent them clips from the movie to use for inspiration. When Stallone asked them to write for Rocky IV
, he sent them scripts from the movie. Survivor was touring with REO Speedwagon at the time.
Peterik told us: "As soon as the delivery came, I remember taking my copy to the pool of our hotel and reading the whole thing in one sitting. I had my notebook open, scribbling down ideas, impressions, catch phrases and concepts as I read. The story had the added dimension of international intrigue with Rocky being pitted against a giant Russian boxer. I soon realized that this battle was about more than just two fighters in a ring, but about the whole struggle between the ideologies of two rival nations. That became my focus as the lyric took shape. Rocky, once again, had to prove to himself and to the world that he had what it took to be champion. I remember pulling the phrase, 'It's you against you' from the dialogue for use in the song. The first line of the song tells the story: 'Two worlds collide, rival nations, it's a primitive clash, venting years of frustration.' Over the next few days we would have the road crew set up our portable Wurlitzer electric piano, an amp and guitar in a separate hotel room so we could work during the day. As usual the music appeared simultaneously with the snippets of lyrics I was coming up with. A few cities down the road we had about 80 percent of the song done."
