The Beatles' early singles really catapulted the band into superstardom in the early 1960s.
And, during their journey, no song was bigger for them than the 1963 single She Loves You.
However, when they were in the recording studio, they had a lot of work to do to get it on the airwaves.
While writing and recording the track with their producer, George Martin, the boss wasn't happy about a final alteration George Harrison made to the song.
Harrison included a sixth interval chord at the end of the track, changing the feel of the final moments of the song. And Martin hated how it sounded.
Paul McCartney came to his pal's defence, however, noting that She Loves You would not be a finished song without it.
"It was corny," he said. "[Martin] thought we were joking. But it didn’t work without it, so we kept it in and eventually he was convinced.
