McCartney has previously been accused of orchestrating their split, after he announced his departure from the band in April 1970 and later that year filed a law suit which called for the group’s formal dissolution.

While he previously said that he undertook the move to protect their music, McCartney explained that Jackson’s footage confirms that he isn’t to blame for their split.

“It was so reaffirming for me,” he told The Sunday Times. “Because it proves that my main memory of the Beatles was the joy and the skill.”

He went on: “The proof is the footage. I bought into the dark side of the Beatles breaking up and thought, ‘Oh God, I’m to blame.’ I knew I wasn’t, but it’s easy when the climate is that way to start thinking so.

“But at the back of my mind there was always this idea that it wasn’t like that, but I needed to see proof. There’s a great photo Linda took, which is my favourite, of me and John working on a song, glowing with joy. This footage is the same. All four of us having a ball.”
McCartney previously hailed the documentary for providing an authentic portrait of The Beatles‘ final years together.

“I love it, I must say because it’s how it was. It just reminds me of – even though we had arguments, like any family – we loved each other, you know, and it shows in the film,” he said.

“It’s a very warm feeling, And it’s amazing just being backstage with these people, making this music that turned out to be good.”

McCartney’s comments come as he prepares to release ‘McCartney III‘ in December, which completes his eponymous record trilogy following 1970’s ‘McCartney’ and 1980’s ‘McCartney III’.

It marks the musician’s eighteenth solo release, which was recorded during the coronavirus lockdown and follows 2018’s ‘Egypt Station’.

Describing the album’s creation, he recently admitted that music has been his “silver lining” during lockdown.
