Recently, I found a few more significant melismas.
"Bad" in the line "It wasn't so bad" is sung with a melisma (D A B), so while it's negated, there's a sense of degree (for that "so"). "Friends" in the line "You still have all your friends" is sung with the same melisma, but here it gives a sense of the entirety of that "all." "Away" in the lines "What could I say / That you ran away" is sung with a similar melisma (D D A B), and here it gives a sense of movement or distance.
