"Sgt. Pepper's Lonely Hearts Club Band (Reprise)" is a repeat of the song at a faster tempo with heavier instruments. While the first track stays largely in the key of G major (except for transient modulation to F and perhaps C in the bridges), the reprise starts in F and modulates back to G. The track opens with a distorted guitar strumming a "Hendrix chord" (dominant 7th sharp 9). McCartney counts 1-2-3-4, and between 2 and 3, Lennon says "bye!".
