The Beatles' "And Your Bird Can Sing"

I just listened to the second disc of the Beatles' Anthology 2.  I noticed a small thing about "And Your Bird Can Sing" (and I also checked the final version on Revolver to verify that it's there too).  There's a downward vocal melisma on the "down" in the lines "When your prized possessions / Start to weigh you down."  Like the melisma on "heavy" that I discovered in "I Want You (She's So Heavy)" earlier this month, this melisma gives a sense of the weight; it's as if the word itself is bent.
