Formal structure of  "Sun King":
Introduction (Section A) 0:00-0:14
Section A (instrumental) 0:14-0:52
Section B 0:58-1:24
Section A' (+ vocals) 1:49-2:26
Comments: Once again, the structural analyses of the "Abbey Road Medley" are very different from previous analyses because of the unique structure of the medley as a whole. However, unlike some of the other medley songs, "Sun King" does contain very clear formal articulations. With that in mind, I've chosen to neglect the standard nomenclature of verse, chorus, middle 8, et cetera, and simply use letters (Section A, Section B), which seems better suited to this song specifically. This provides a very nice, clean ternary form: A B A'.
The two A sections are practically identical except for the addition of the vocals (the tempo during A' is also a little faster, and the endings are a bit different since they lead to different places).
The B section - despite not being a true verse - uses the "third quarter verse structure" that the Beatles used rather frequently in their earlier years ( “I Saw Her Standing There”,  "A Hard Day's Night",  "Things We Said Today",  "I Don't Want to Spoil the Party",  "No Reply",  "Eight Days a Week",  "I Need You",  "The Night Before",  "I'm Looking Through You",  "Wait",  "You Won't See Me",  "Octopus's Garden", and  "Her Majesty"). In this case, the first, second, and fourth quarters all use the lyrics "Here comes the sun king", while the third quarter uses the lyrics "Everybody's laughing, everybody's happy". The chords are different, too, but consideration of that will have to wait until my harmonic analysis of this track.
