When The Beatles broke up, George Harrison and John Lennon were not happy with former bandmate Paul McCartney. Lennon disparaged his solo music and wrote pointed lyrics about McCartney. Harrison said that he would never work with him in a band again. They talked trash about him privately too, but they made it clear that the people they were talking to shouldn’t join in.When The Beatles broke up, McCartney sued the band in order to take control of their catalog from manager Allen Klein. This, coupled with festering irritation over McCartney’s behavior in the studio, infuriated his bandmates. Lennon wrote the brutal “How Do You Sleep?” about McCartney, and Harrison said publicly that he wouldn’t want to work with McCartney again.“To tell the truth, I’d join a band with John Lennon any day, but I couldn’t join a band with Paul McCartney, but it’s nothing personal,” he said, per the book George Harrison on George Harrison: Interviews and Encounters. “It’s just from a musical point of view.”
