The Zombies' "Indication"

The third (and final) thing I noticed while listening to the Zombies' The Decca Stereo Anthology is in the backing vocals in "Indication."  For the last line of the verses, the backing vocals have a consist descent.  For the first two verses, that melodic arc emphasizes the lyrics:  "Tied down every day and every night" and "I won't be the one to settle down."  Both have "down" in the line, and the melody descends.
