Editing Rubber Soul (section)

===Band dynamics===
While Martin recalled the sessions as having been "a very joyful time",{{sfn|The Beatles|2000|p=197}} Smith felt "something had happened between ''Help!'' and ''Rubber Soul''", and the family atmosphere that had once characterised the relationship between the Beatles and their production team was absent.{{sfn|Womack|2017|p=311}} He said the project revealed the first signs of artistic conflict between Lennon and McCartney,{{sfn|Kruth|2015|p=82}} and friction within the band as more effort was spent on perfecting each song.{{sfn|Womack|2017|p=311}}{{refn|group=nb|McCartney began to insist that, when recording his compositions, the Beatles adhere to arrangements he had decided on in advance.{{sfn|Ingham|2006|p=185}} Smith said that McCartney was frequently critical of Harrison's playing, foreshadowing a condescending attitude on McCartney's part that would lead to Starr temporarily leaving the band three years later.{{sfn|Kruth|2015|pp=82–83}}}} This also manifested in a struggle over which song should be the A-side of their next single, with Lennon insisting on "Day Tripper" (of which he was the primary writer){{sfn|Jackson|2015|p=263}} and publicly contradicting EMI's announcement about the upcoming release.{{sfn|Miles|2001|pp=214, 216}}

In addition, a rift was growing between McCartney and his bandmates as he continued to abstain from taking LSD.{{sfn|Sounes|2010|pp=127–28}}{{sfn|Gould|2007|p=388}} The revelations provided by the drug had drawn Lennon and Harrison closer,{{sfn|Sounes|2010|pp=127–28}}{{sfn|Kruth|2015|p=96}} and were then shared by Starr when, during the band's stay in Los Angeles that August, he agreed to try LSD for the first time.{{sfn|Rodriguez|2012|pp=54–55}}
