Comments: "I Need You" is another song in which the third quarter of each verse is slightly different from the other three quarters (a pattern found in  "A Hard Day's Night",  "Things We Said Today",  "I Don't Want to Spoil the Party",  "No Reply", and  "Eight Days a Week"). This one, however, is the first Harrison composition to employ this tactic.
Here are the lyrics of the first verse divided into these four sections:
You don't realize how much I need you
Love you all the time, would never leave you
Please come on back and see just what you mean to me
I need you
The chords of the first, second, and third divisions are nearly identical (A, D), while the chords of the third division are entirely different (F#m, C#m, Bm). The rhyming of the lyrics follow suit. Harrison has clearly learned this lesson from the Lennon/McCartney original  "I Don't Want To Spoil the Party", which is very, very similar.
Despite being rock 'n' rollers, The Beatles were very polite in their lyrics. Of the 213 songs recorded by the Beatles and released on their albums, 25 (12%) use the word "please":
