"I Feel Fine"

A couple days ago, I figured out the solo in "I Feel Fine."  The next day (yester-day), I was thinking about the song again and noticed an interesting feature.  In the lines "I'm so glad that she's my little girl / She's so glad; she's tellin' all the world," the first halves ("I'm so glad" and "She's so glad") are sung by multiple voices.  Because there are more voices, there's a sense of the degree of those "so"s.

"Lend Me Your Comb"

Yester-day, I was thinking about Carl Perkins' "Lend Me Your Comb," and I realized something that's also true of the Beatles' BBC version.  In the lines "Just wait till I / Straighten my tie," the semantic sense is spread across the line break, and this particular structure actually forces the listener to "wait" until the words in the second line complete the meaning.
