On 1 June, the Beatles and some of their friends enhanced the festive nautical atmosphere by adding sounds such as chains, bells, whistles, tubs of water and chinking glasses, all sourced from Studio 2's trap room. To fill the portion after the lyrics refer to a brass band playing, Martin and Emerick used a recording from EMI's library, splicing up the taped copy and rearranging the melody. Lennon shouted part of the mid-song ship's orders in an echo chamber. In the final verse, he repeats Starr's vocal lines in a manner that Gould likens to "an old vaudevillian with the crowd in the palm of his hand". Riley recognises the song's mix of comedy as reminiscent of "The Goon Show" with satire inspired by Spike Jones. Donovan later said that "Yellow Submarine" represented the Beatles' predicament as prisoners of their international fame, to which they reacted by singing an uplifting, communal song.
