When I listened to Argent last week, I noticed a couple small things in "Lonely Hard Road."
"Away" in the line "Like a fool, I made her run away" is sung with a melisma (F F Eb C), musically giving a sense of movement or distance.
"Walking" in the line "So I'll just keep walking" in the slower section at the end is also sung with a melisma (F Eb Eb), musically giving a sense of movement but also of that continuing.
