"Little Girl"

When I listened to Good Times! recently, I noticed a lyrical ambiguity in "Little Girl," specifically in the lines "Cheer up; I'll turn your frown sunnyside up / Come fill your cup."  "Come" could be either a continuation of "I'll" ("I'll turn your frown sunnyside up / [And I'll] come fill your cup") or an imperative that's separate from the preceding line.  The structure of the following verse (with its lines "Stand up; we'll go to town / Go for a ride") suggests the former, but I think the latter is also viable.

"Little Girl"

The first two lines of "Little Girl" are "Little girl, don't you be brought down / Cheer up, I'll turn your frown sunnyside up," and the "down" and "up" are illustrated through the melodies to which they're sung.  "Be brought down" is sung to descending notes (D C# A), and "up" is sung with an ascending melisma (E F# G#).
