"How Can You Walk Away"

I listened to Keats yester-day and noticed a few things in "How Can You Walk Away," specifically in the chorus:

How can you walk away
How can you leave
How can you turn away
When our love was incomplete

Both "away"s (Bb G F) and "leave" (F D) are sung with melismas, which all give a musical sense of movement.  There's also a slant rhyme between "leave" and "incomplete," so the nature of being "incomplete" is demonstrated poetically.
