In 1969, when the Beatles were recording the album that became Abbey Road, Paul McCartney would come in every day to record a vocal track. (He lived near the studio, so it was easy for him to drop by.) The vocal he was trying to get right was “Oh! Darling” — a song that, some years later, John Lennon would say was better suited to his voice than Paul’s — and each day Paul would perform one take and one take only. There’s some serious shouting on that song, and Paul was taking care to protect his voice; several takes might do damage that would take time to heal.
Six years earlier, when the lads were recording their first album, they did the whole thing — fourteen songs — in one day, and they saved “Twist and Shout” for the end because John knew that once he had done that one, he wouldn’t have any voice left to do anything else.
