 Conti, who was too busy with the first two "Karate Kid" films at the time, would return for "Rocky V" and "Rocky Balboa".Conti's famous piece of music from the Rocky series, "Gonna Fly Now", does not appear at all in "Rocky IV" (the first time in the series this happened), though a few bars of it are incorporated into DiCola's training montage instrumental.Songs from the movie included "Living in America", by James Brown, and also music by John Cafferty ("Heart's on Fire", featuring Vince DiCola), Survivor, Kenny Loggins, and Robert Tepper.
