After leaving Chicago , Cetera continued his streak of success . His first single , " Glory of Love " was used as the theme song for the film '' The Karate Kid Part II '' . Co-written by Cetera , David Foster , and Diane Nini , Cetera has said it was written originally for the film , '' Rocky IV '' . It was a number one hit on the '' Billboard '' Hot 100 and Adult Contemporary charts in the US in 1986 , and achieved similar success throughout the world . It went on to win an ASCAP Award for Cetera for Most Performed Songs from Motion Pictures and a BMI Film & TV Award for David Foster for Most Performed Song from a Film . It was also nominated for both an Academy Award and a Golden Globe Award in the category of Best Original Song , as well as a Grammy Award for Best Pop Vocal Performance by a Male Artist . He performed a shortened version of the song live at the 59th Academy Awards ceremony . In two interviews Cetera gave in 1987 , he discussed people 's confusion about " Glory of Love " , and said they thought initially that it was a new song by Chicago . By February of that year , however , he had achieved enough recognition as a solo performer to win the American Video Award for " best new artist "
