 According to author Bruce Spizer , the line @-@ up for the basic track , before overdubs , was Lennon ( vocals , acoustic guitar ) , Harrison ( electric guitar ) , Preston ( organ ) , Voormann ( bass ) and White ( drums ) . Lennon later recalled of the recording : " Phil ( Spector ) came in and said , ' How do you want it ? ' And I said , ' 1950s ' and he said ' Right ' and BOOM ! ... he played it back and there it was . " The song uses a similar amount of echo to 1950s Sun Records recordings .
