I recently got Beach Boys' Party!/Stack-o-Tracks (the two-albums-on-one-CD reissue), and when I listened to it for the first time last night, I noticed a couple things.
In "There's No Other (Like My Baby)," there's a melisma'd "so" (A G F) in the first verse: "There's a story I want you to know / 'Bout my baby and how I love her so." In a musical way, this gives a sense of degree.
Similarly, there's a melisma'd "proud" (also A G F) in the second verse: "Walkin' down the street in a crowd / Lookin' at my baby, feelin' so proud." This, too, gives a musical sense of degree or amount.
I referenced the version by the Crystals (which - according to the liner notes - was the basis for the Beach Boys' version), and while it's in a different key and some of the lyrics are a bit different, it also has these features.
In comparing them, I learned the chords for both and discovered that the Beach Boys changed one chord. In the Crystals' version (in D major), the verses are |: I vi IV V :|. The Beach Boys (along with lowering the key to Bb major) play |: I vi ii V :|.
(For what it's worth, Brian Wilson did a similar thing with "County Fair" and "I Do.")
