Paul McCartney has admitted Yoko Ono's presence in the studio during The Beatles' recording sessions infuriated the band.
McCartney admitted things were tricky when John Lennon and Ono first met and it did frustrate the band at the time. He told Q Magazine: "Because we'd been such a tight-knit group, the fact that John was getting pretty serious about Yoko at that time, I can see now that he was enjoying his newfound freedom and getting excited by it.
But when she turned up at the studio and sat in the middle of us, doing nothing I still admit now that we were all cheesed off. But looking back on it - [me and Yoko] have talked about this - I think she realizes it must have been a shock for us. But lots of things that went down were good for us, really. At the time though, we certainly did not think that."
Despite his comments, McCartney previously denied that she was responsible for splitting the band and instead placed more of the blame of The Beatles break-up on businessman Allen Klein, who succeeded manager Brian Epstein following his death in 1967.
