The song's five-bar bridge is filled by a French horn quartet. Womack credits the recording's use of a brass ensemble with distorted electric guitars as an early example of rock fusion. MacDonald agrees, describing the track as an overture rather than a song, and a "fusion of Edwardian variety orchestra" and contemporary hard rock. Hannan describes the track's unorthodox stereo mix as "typical of the album", with the lead vocal in the right speaker during the verses, but in the left during the chorus and middle eight. McCartney returns as the master of ceremonies near the end of the song, announcing the entrance of an alter ego named Billy Shears.
