Comments: The reprise of the title track to Sgt. Pepper's Lonely Hearts Club Band employs only the chorus from the original - neither verse, nor the break/middle 8 appear in this version. Conversely, the chorus (used exclusively in the reprise) was only heard once in the original.
The key change from F major to G major is worth a brief note because it helps delineate the structure. In this abbreviated reprise, with just two choruses plus transitional material on either side, the modulation serves as the halfway point, separating the two choruses. This modulation is something I will look at in more detail when I do a harmonic analysis of this track.
