John Lennon was not a fan of one of Paul McCartney's songs. According to a Beatles engineer, he made his hatred of the song very clear.By the end of the 1960s, Paul McCartney was beginning to get on John Lennon’s nerves. All The Beatles found him domineering in the studio, overly focused on perfecting his songs. One of the songs he spent an exceptionally long time on was “Ob-La-Di, Ob-La-Da.” He was a perfectionist about the production, much to his bandmates’ irritation. It didn’t help that Lennon disliked the song and did not try to hide it.
McCartney dragged The Beatles through endless takes of “Ob-La-Di, Ob-La-Da” while working on the White Album.
“The previous week’s work was a typical study in frustration,” audio engineer Geoff Emerick wrote in his book Here, There and Everywhere: My Life Recording the Music of the Beatles. “We’d worked endlessly on just two songs: Lennon’s ‘Revolution’ and McCartney’s ‘Ob-La-Di, Ob-La-Da,’ done over and over again until we were all sick to death of them. Nonetheless, here we were again, breathing in the same stale studio air, working on those same two tracks.”
