music question

two questions about the wonderful soundtrack to this...

i bought it and it does not have two of my favorite songs, unfortonately. one is the music that almost always plays when frederick douglass is quoted; another is the slow version of bonnie blue flag that is usually the theme for robert e. lee. can anyone tell me the name of frederick douglass's theme, and if possible where i could find both of these? thanks!

baby can you dig your man?
