When I was in college I had a very difficult professor who would do pushups in class and was in general just very scary to me. The one and only thing that got me through that class was pumping myself up for the final exam by putting on 1982's Rocky III and watching the training montage with "Eye of the Tiger" playing.
Frankly, not only can I not imagine getting through college without this song, I can't imagine getting through life without it.
Yet if director/star Sylvester Stallone had gotten his way, it would have been an entirely different song used in the film. What song was it?
