It came as a welcome relief that John and Paul, along with Neil Aspinall, planned a quick trip to New York on May 11, where several press events had been scheduled to announce Apple Records in the States. Friends agreed that getting John away might do him a world of good; being alone, with just Paul to steady him, might have a calming influence. Paul was grappling with his own set of anxieties. “We wanted a grand launch,” Paul said, “but I had a strange feeling and was very nervous.” Drugs, he later admitted, may have been at the root of his problem. – Bob Spitz, The Beatles: The Biography
“It was widely believed that Lennon’s relationship with McCartney was at its lowest point at this time, but Van Scyoc {Gary Van Scyoc, bassist on Some time in NYC, 1972} saw ample evidence that this simply wasn’t the case. “You would read in the New York Post that they were at each other’s throats. I had a copy of the paper in my kit bag, and as I walk into the session, John is on the phone with Paul in Scotland for an hour-and-a-half and they’re yakking it up. That doesn’t really sound like two people who are at each others throats, does it?”
