 On 1 June, the Beatles and a group of their friends created a nautical atmosphere over the pre-recorded basic track, by mixing sounds such as gongs, whistles and bells with an assortment of Studio 2's sound effects.To fill the portion after the lyrics refer to a brass band playing, Martin and Emerick used a Sousa march recording, sourced from EMI's library, splicing up the taped copy and rearranging the melody.Lennon recorded the track's superimposed voices in an echo chamber, supporting Starr's lead vocal in a manner that Gould likens to "an old vaudevillian with the crowd in the palm of his hand".
