McCartney’s songwriting and performing partnership with Lennon, despite its fractiousness, was one of the most notable in popular music (his relationship with Ono was also terse). Pinter invited him to parties, Dylan introduced him to cannabis. Wilson and McCartney were friends across decades, if never close, and competitive mutual influences. De Kooning, befriended through his wife’s father, inspired him to paint. He performed on stage with his friend Ginsberg, got another friend, Hamilton, to design a famous cover, and played a studio session with Wonder. Lynch interviewed him about transcendental meditation. Unfortunately available biographies tend to lack objectivity.
