Despite the tensions between The Beatles during the Let It Be sessions, Paul couldn’t help but boast one of the best qualities about the group.
In Get Back film, Paul tells director Michael Lindsay-Hogg that the best bit of The Beatles “always has been and always will be is when we’re backs against the wall and we’ve been rehearsing, rehearsing, rehearsing.”
He continued to say that even if The Beatles were at a big place like Twickenham Studios, they’d still be able to play their music well. So, once The Beatles started making their music, their problems outside the recording studio suddenly disappeared. That is certainly obvious in Jackson’s very long documentary.
The Beatles’ recording sessions were always good because “no matter what our personal troubles were, no matter what was happening on the business front, the minute we sat down to make a song we were in good shape,” Paul wrote. “Right until the end there was always a great joy in working together in the studio.” (Cheatsheet)
But Geoff Emerick revealed how he was "physically ill" due to the horrific atmosphere of the band's final years working together. He called the experience an "ugly divorce". Paul McCartney and John Lennon promised peace during recording.
After The Beatles' hugely popular 1968 record, The White Album, the pressure was on for the Fab Four to release another smash hit. Emerick described the atmosphere behind the scenes during the writing and recording of The White Album as dreadful. He explained: "The group was disintegrating before my eyes." (Express)
Emerick said the recording experience during those days in the summer of 1968 was "ugly". He continued: "Like watching a divorce between four people. After a while, I had to get out."
After that, Emerick quit working for The Beatles and would not return to record their follow-up album, Abbey Road. But the band and their producer, George Martin, coaxed him back into working on the Fab Four's music. However, he was still reluctant at the time. And it's no wonder why after describing working on The White Album as "a nightmare". (Via Musicradar)
Emerick said: "I was becoming physically sick just thinking of going to the studio each night. I used to love working with the band. By that point, I dreaded it. Getting out was the only thing I could do." His return was unexpected, but he had certain assurances from members of the band - who had just recorded large chunks of their final album, Let It Be - on a better atmosphere.
He continued: "It came about through a conversation George Martin had with Paul [McCartney]. I had left EMI, but I was employed by The Beatles and was overseeing the construction of a new studio for them at Apple. After Let It Be, which I understand was not very pleasant for anybody, Paul was very keen to make a record the way the band used to."
Emerick said Paul McCartney wanted him and Martin behind the production console once again. He added: "He [McCartney] said things would be better than what they had been." And Emerick took him at his word - and he wasn't the only member of the band who wanted to cultivate a better culture during recording: John Lennon also agreed with McCartney.
Emerick said: "John said the same thing to George Martin. In the back of my head I might have had some reservations, like: 'Well, we'll see…' But I was surprised and pleased at how everybody got along."
