"Goin' Down"

I watched "Monstrous Monkee Mash" yester-day and noticed a small feature in "Goin' Down."  In the line "Don't want no more" near the end of the third verse (the one starting with "I wish I had another drink..."), the "more" is sung with a melisma (E G), so while it's negated, there's a sense of that abundance.
