For four decades Beatles fans have blamed Yoko Ono for the band's demise. However, in a revealing interview with Sir Paul McCartney, the legendary singer has shed light on many aspects of himself and the Beatles, as well as removing blame from Yoko Ono and transposing it onto Allen Klein, the Beatles' manager who took over proceedings after the death of their original manager, Brian Epstein. 

In this new interview that McCartney's given to David Frost, he admitted "[Yoko] certainly didn't break the group up, the group was breaking up". E! reports that also told Frost what a great influence she had on John Lennon. After the breakdown of the Beatles Lennon went on to forge a hugely successful solo career, including the wildly popular and iconic song 'Imagine'. "I don't think he would have done that without Yoko, so I don't think you can blame her for anything. When Yoko came along, part of her attraction was her avant garde side, her view of things, so she showed him another way to be, which was very attractive to him," McCartney said. "So it was time for John to leave, he was definitely going to leave." 

The Frost/McCartney interview will be aired on Al Jazeerah English, and is the longest interview given by McCartney for decades.
