Formal structure of  "Yes It Is":
Intro (verse) 0:00-0:05
Verse 1 0:05-0:32
Verse 2 0:32-1:00
Middle 8 1:00-1:18
Verse 3 1:18-1:48
Middle 8 1:48-2:05
Verse 4 2:05-2:31
Coda (verse) 2:31-2:42*
Comments: The coda features a fascinating chord progression that functions similarly to a deceptive cadence, but technically it isn't one:
E G#7 A B7 E
Yes it is, it's true. Yes it is, it's true.
I III7 IV V7 I
The G#7 on the word "true" is completely unexpected, having never been heard or even hinted at previously in this song, and it delays the final resolution to tonic, just like a textbook deceptive cadence does. That being said, it lacks the V to vi motion that defines a deceptive cadence, thus it cannot be called one.
