“Eye of the Tiger”, the most well-known song by Survivor, held the #1 spot on the Billboard Hot 100 chart for six consecutive weeks in the summer of 1982 and topped charts in several other countries including Canada, Japan, Norway, Finland and the UK. It also won the band a Grammy for Best Rock Performance by a Duo Or Group with Vocal.

Written by guitarist Frankie Sullivan and keyboardist Jim Peterik, the lyrics describe someone training hard to overcome hardships – fitting well its original intention, over the training montage in the film Rocky III. It has since become an anthem of sports events, particularly fighting ones, and is tied with “Gonna Fly Now” for Rocky Balboa’s theme song.

According to The Billboard Book Of Number 1 Hits, within 90 minutes of seeing an early tape of the film, the band had the song written. They based the title and lyrics on a line repeated several times by a boxing trainer in the film – “eye of the tiger.”
