Comments: First song (not just first Beatles song) to feature a fade-in intro.
Another four-part verse structure in which the third part contrasts the other three parts (just like  "A Hard Day's Night",  "Things We Said Today",  "I Don't Want to Spoil the Party", and  "No Reply"):
Ooo I need your love babe, guess you know it's true
Hope you need my love babe, just like I need you
Hold me, love me, hold me, love me
I ain't got nothing but love babe, eight days a week.
Verses 1 and 3 share identical lyrics, as do verse 2 and 4. Interestingly, vocal harmony is added in this contrasting third verse subsection, but only on verses 2 and 4 - not on verses 1 and 3.
2-part coda: first part based on repetition of the title lyrics (which comes from the end of the verse); second part similar to the introduction but independent from the rest of the song.
