Premise: The upward leaping orchestral figure anticipates the word, top, but the sung line does not, and at the punchline, But if Baby I'm the bottom, / You're the top, both Billy and Reno (I'm and You're) share a melodic line at the top of their respective ranges.

Hypothesis: The duo share a line at the top of their vocal ranges, but there is room for improvement.
Relation: neutral
