The Rocky theme, best known as Gonna Fly Now, was written by Bill Conti for the original 1976 film Rocky, starring Sylvester Stallone as boxer Rocky Balboa. It became famous through the film's training montage, in which Rocky runs through Philadelphia and up the steps of the Philadelphia Museum of Art. The music has since become a cultural shorthand for perseverance and training, reused in sequels, parodies, sports broadcasts and countless online edits, keeping it instantly recognisable decades later.
