Yester-day, I realized that in "Whistle In," the "all" in the line "All day long" has a longer value than any other note and that (along with
the melismas that I noted years ago) this provides a sense of duration. I couldn't figure out all of the precise note values (which is why I don't have notation), but "all" is sung with a half note, and the other notes are quarter notes or shorter.
