"Kellogg's Jingle"

Yester-day I was thinking about the "Kellogg's Jingle" (included as a bonus track on the deluxe edition of The Monkees).  I recently came across some notation for it (vocal melody, bass, and finger snaps) that - as far as I can tell - I wrote out in late January 2017 when I figured out those parts.

Anyway, I realized a small thing about the vocal melody:

The text here is "K E double L / Oh double good / Kellogg's best to you."  Each "double" is sung to a pair of eighth notes, so - compared to the surrounding quarter notes - there are double the number of notes for the beats in which "double" is sung.
