I was thinking about "Help Me, Rhonda" yester-day, and I realized that the line "She was gonna be my wife, and I was gonna be her man" contains a sort of chiasm (she | my || I | her). This structure reflects the reciprocity that this relationship had before "she let another guy come between us."
While referencing the recording to verify the lyrics, I also noticed that "fine" in the line "Well, Rhonda, you look so fine" is sung with a melisma (C# B# A# in the lead vocals), giving a sense of degree (for "so").
These features are also present in the version on Today! ("Help Me, Ronda").
