The title of this song is from William Shakespeare’s Julius Caesar. Specifically, it is the lines spoken by Marcus Antonius (Mark Anthony) as he addresses a crowd of Romans after Julius Caesar’s murder in Act III, Scene 2:

Friends, Romans, country men, lend me your ears; I come to bury Caesar, not to praise him. The evil that men do lives after them, the good is oft interred with their bones; so let it be with Caesar.

Bruce Dickinson has often quoted the lines from Shakespeare during live performances, before the song starts.

The actual theme of the song doesn’t have anything to do with the play however. The lyrics continue the album’s story about the seventh son of a seventh son, who is about to be born. Both God (the good) and Satan (the bad) want to have control over the child, who will one day possess great powers.
