risin' up, back on the street
did my time, took my chances
went the distance, now i'm back on my feet
just a man and his will to survive
so many times, it happens too fast
you change your passion for glory
don't lose your grip on the dreams of the past
you must fight just to keep them alive

it's the eye of the tiger, it's the cream of the fight

risin' up to the challenge of our rival

and the last known survivor stalks his prey in the night

and he's watchin' us all in the eye of the tiger
face to face, out in the heat
hangin' tough, stayin' hungry
they stack the odds 'til we take to the street<
