"California Girls"

In the two live versions of "California Girls" on 1967: Sunshine tomorrow, one line is "The midwest farmers' daughters, well, they all make you feel alright" (instead of "The midwest farmers' daughters really make you feel alright" as it is in the studio version).  "They" is grammatically unnecessary, but the redundancy that it creates with "daughters" hints at this entirety ("all").

"Country Air"

The line "Mother Nature, she fills my eyes" in "Country Air" contains a pleonasm, and while "she" isn't necessary grammatically, the redundancy that it creates with "Mother Nature" matches the abundance implied by "fills."

"Aren't You Glad"

I recently listened to 1967: Sunshine tomorrow again and noticed a handful of small points.

In "Aren't You Glad," some of the notes in the bass part highlight the meaning of the lyrics, specifically in these sections:

You know that I've been a long time needin' you

You say that you've been a long time needin' me

And don't you know that there's so much more to come

You know that I'll be a long time lovin' you

I hope that you'll be a long time lovin' me

And don't you know that there's so much more to come

Under these, the bass plays something like:

The notes beneath each "long" and "so" are longer than the surrounding notes, and these greater values give a sense of duration (for "long") and degree (for "so").
