"Eternity Road"

In "Eternity Road," "road" is sung with a glissando from D to C (in one vocal part, at least).  Musically, the word is stretched out, which gives something of a sense of "eternity."  "Load" in the next line - "Carrying your heavy load" - is sung with a descending melisma (F D C), which gives a sense of the "heavy" weight, as if the melody itself is faltering beneath it.
