The calliope-like instrument heard in the opening bars is an electric 12-string guitar plugged directly into the recording console. Due to recording logistics, this created an unusual situation in which the player had to perform the instrument in the control room, away from the rest of the musicians, who could not hear his playing in the regular recording space. Much of the track's rhythmic accompaniment is provided by two accordions playing a shuffle beat in a manner similar to "California Girls" (1965). During the bridge, the players performed a technique known as a "triple bellow shake" to make the accordions sound like a violin.
