In the line "Don't you be so bad" in "Driva Man," both "so" and "bad" are sung with melismas (I think "so" is sung to the notes F D D C Bb and "bad" to the notes C Bb) giving a sense of degree.
That each verse ends with the lines "Ain't but two things on your mind / Driva man and quittin' time" illustrates the predominance of those two things.
