The Beatles‘ “Can’t Buy Me Love” is a simple antimaterialistic song. During The Beatles’ early career, Paul McCartney came to believe the title of “Can’t Buy Me Love” is false. He explained how a date he had prior to filming A Hard Day’s Night changed his mind regarding the song.
In the 1997 book Paul McCartney: Many Years From Now, Paul remembered going to Miami before filming A Hard Day’s Night. “Miami was incredible,” he opined. “It was the first time we ever saw police motorbike outriders with guns.”
Paul decided to document his experience. “I’ve got photographs I took out of the car window,” he recalled. “It was amazing.”
