Comments: Similar to  "A Hard Day's Night",  "Things We Said Today",  "I Don't Want to Spoil the Party", the verse structure of "No Reply" can be divided into four parts:
This happened once before, when I came to your door, no reply.
They said it wasn't you, but I saw you peep through your window.
I saw the light, I saw the light.
I know that you saw me, 'cause I looked up to see your face.
The first, second, and fourth of these subsections are essentially musically identical (the same chords, same character, roughly the same melody), but the third part is different (different chords, different character, very different melody, plus the addition of vocal harmonies and huge cymbal hits both noticeably absent from the other three subsections).
No intro. Coda is the only time you hear the title lyrics, and is musically (but not lyrically) based on the third part of the verse.
