EXCLUSIVE: Paul McCartney's Most Abusive Rant Ever Laid Bare — and Why It Was Driven By His Hatred for John Lennon
Insiders say tensions turned deeply personal, fueled by betrayal.
Sir Paul McCartney’s most explosive private rant has resurfaced amid fresh scrutiny over The Beatles’ breakup – a furious note driven by his deepening resentment toward John Lennon and the bitter power struggle that followed the band’s collapse.
The 83-year-old musician, who had spent nearly half his life in creative partnership with Lennon before the Beatles split in 1970, is the subject of renewed attention following the release of Morgan Neville’s documentary Man on the Run.
It charts McCartney’s prolific post-Beatles decade, his relationship with Linda McCartney, and his enduring emotional connection to Lennon – as tensions between the former bandmates escalated.
The period also coincided with disputes over management, particularly involving Allen Klein, who represented Lennon, George Harrison, and Ringo Starr, but whose involvement McCartney strongly opposed.
Amid that conflict, McCartney’s anger became explicit in a now-notorious letter to Klein.
