For instance, I grew up on Conway Twitty's country-western rendition of the famous Irish ballad, "Danny Boy." There are a few varying interpretations of the song, but most would settle on either the story of a parent sending his son off to war or perhaps a dying father speaking to his only son. It's a somber, melancholic song to be sure and it is often played at funerals for this reason. Once I was old enough to appreciate the lyrics, however, I noticed a strange incongruity between the subject matter and the tone of Conway Twitty's version.
