The 'music score'

The music score for Blind Fist of Bruce sounds like it was taken from a library of music; that's typical of old school kung fu movies. I am a music buff and I wonder if someone out there can please help me identify the original films that contained the original music cues...and who was the composer of those cues

)The music that plays during the climax sounds like Jerry Goldsmith music.
)The music during the main title sounds like music from a spy movie.
)Who composed the mellow melodramatic music when Master Yeh asks his sifu/teacher about his family?
