From Rolling Stone, one to read with your coffee.
They had so much material to record, and so much distaste for each other, that they were recording in three studios, sometimes 12 hours a day. Each of the Beatles treated the others as his supporting musicians – which made for some spectacular performances and some explosive studio moments: Lennon storming out on the tedium of recording McCartney’s “Ob-La-Di, Ob-La-Da”; Ringo quitting the group for almost two weeks after Paul berated his drumming on “Back in the U.S.S.R.”; Harrison bringing in his friend, guitarist Eric Clapton, just to win rightful consideration for “While My Guitar Gently Weeps”; McCartney, in a shocking display, telling off George Martin in front of the band; and Geoff Emerick finally walking out, quitting his work with the Beatles over their turbulent and nasty behavior. When it was finished, The Beatles was regarded as a disjointed masterpiece, the sound of a band in top form that nonetheless no longer had hope. In later years, McCartney would refer to it as “the Tension Album.”
