Pattie Boyd chose The Beatles’ “A Day in the Life” as her favourite song, despite her close personal connection to George Harrison and several Beatles songs associated with her life. Her choice reflected not sentimentality but astonishment at witnessing the band’s transformation into an experimental force capable of creating music unlike anything she had heard before.

The five-minute closing track on *Sgt. Pepper’s Lonely Hearts Club Band* impressed Boyd through its shifting tempos, orchestral climax and expanding scale. She recalled hearing the song develop in fragments at Abbey Road and at home, as Harrison brought back recordings and further parts were added, while George Martin and the band embraced increasingly ambitious musical experimentation.
