"Only with You"

A couple days ago, I listened to a two-albums-on-one-CD reissue of Colin Blunstone's Planes and Never Even Thought.  He covers "Only with You" on Planes, and I noticed a feature in his version that's also in the Beach Boys' original.  In the lines "Before love had always had / Its ups and downs," "downs" is sung with a descending melisma (B# G#, I think), musically giving a sense of the word's meaning.
