John Lennon and Yoko Ono’s marriage wasn’t always peace and love.

From late 1973 to 1974, Lennon began “Lost Weekend” in Los Angeles while separated from his wife. Ono had kicked the singer/songwriter out of her home after he had “loud, boisterous sex” with another woman at a party.

While Lennon was eager to return to Ono, he was wary of her returning home. That’s when he got by with a little help from an unlikely Beatle.

“Sir Paul McCartney offered Yoko to talk to John in Los Angeles about the breakup,” Elliot Mintz, a friend of the couple, told Fox News Digital. “He seemed grateful for the invitation.”

The former Los Angeles radio and TV anchor, who met the couple in the early ’70s, has written a new memoir: “We All Shine: John, Yoko and Me” with the approval of their son, Sean Lennon. In the book, he describes how McCartney gave sound advice to the heartbroken Lennon on how to win his love back.

“Paul came here, he had a meeting with John,” Mintz said. “His advice to her was, ‘You can’t just say you’ve changed. You have to show it. You have to prove it. It’s like dating her again. You have to bring her flowers, you have to do that. You have to take her out to dinner. You have to show her how important she is in your world.'”

Mintz said Lennon took McCartney’s advice “to heart”. It worked.

“Yoko welcomed him into their home and they continued their relationship,” Mintz said. “It wasn’t fun being around John on the missing weekend. Remember that John was never single. He had always been married since his days at Liverpool. So this was a time when he was sowing wild oats. While Yoko was having trouble finding herself in her marriage, she brought him here (to Los Angeles) a) they sent.”

“He actually lost it over the lost weekend and climbed the ladder to her heart,” Mintz mused.

At the time of the couple’s separation, their assistant May Pang said that Ono wanted him to date Lennon in the hope of keeping her company. Lennon and Pang hit the road A whirlwind 18-month relationship.

“I’ve met him a few times,” Mintz said of Pang. “She is an outspoken woman who would be an ideal companion to send to Los Angeles to be with John. She didn’t smoke, she didn’t drink, and she truly had his best interests at heart. I believe that’s true. I have a good feeling about her.”

Mintz continued: “He tends to portray the lost weekend as a period of great creativity for John, a period of intense love between the two.” “I just saw it a little differently. I don’t doubt for a moment that May was in love with John for all the right reasons. I would never question or second-guess a woman’s ambitions in that area. And of course, what they share will remain between the two of them, but I will always “I saw my language differently from him.”

Mintz said the lost weekend was “the most demoralizing two years John ever lived”, referencing the 1945 Billy Wilder film.

“John went completely off the rails,” Mintz said. “He spent most of his time in Los Angeles under the influence of substances, staying up all night, not producing much. When I talked to him, he sounded more depressed than happy.”

Mintz claimed that during their conversation, Lennon told Ono he was ready to return.

“We talked about how he was ready to return to Yoko,” Mintz said. “He would call Yoko ‘Mom’ and he would say to me, ‘Please tell Mom I’m ready to come back.’ Dutifully, when we talked at the end of each day, Yoko would ask, ‘How’s it going?’ “I said, ‘Look, he really feels like he’s gotten his act together and he’s ready to come home.’ And for a very long time, Yoko kept telling me, ‘No, it’s not like that.'”

Mintz’s book described how, in 1972, Lennon became drunk while watching the presidential election results between Richard Nixon and George McGovern at the anti-war activist station. Jerry Rubin’s apartment in New York City. Lennon and Ono were guests of the party held there.

After Lennon’s drinking got worse, he had sex with another woman. Mintz said Ono “could clearly hear them talking about it.”

A party guest tried to drown out the noise by playing a Bob Dylan song. It didn’t work.

“Throughout all this, Yoko sat on the couch in confusion and embarrassment as the other guests began to awkwardly get up, until she realized their coats were in the bedroom where John had sex,” Mintz said. he wrote.

Mintz said he received a phone call from a hungover Lennon the next morning. He slept on the couch that night.

“These things happen,” Lennon defended. “A man is cheating on his wife… If I wasn’t famous, no one would care.”

Mintz wrote that Ono felt differently.

“I can forgive him. But I don’t know if I can forget what happened,” he said. “I don’t know if it will ever be the same again.”

Following their separation, Lennon and Ono renewed their vows in 1975. They welcomed their son Sean Lennon.

“One of the most popular theories is that John became a recluse from 1975 to 1980, and Yoko locked him in their bedroom, where he turned into almost a Howard Hughes figure, drunk almost constantly,” Mintz told Fox News. Digital. “He was actually busy raising his son.”

“We joked about it,” Mintz said. “Even during the five years when she wasn’t making music, she was creative… Another myth that has been put forward is that Yoko hired a hypnotist to influence John and come back (to their apartment). This is not true after Dakota left. John knew I was seeing a hypnotist. I shared my experiences.” he remembered and said: ‘I kicked everything but do you think that hypnotist guy could do it?'”

“I hired the hypnotist to fly from Los Angeles to New York,” Mintz continued. “When the session was over, John called me. ‘How did it go?’ I said. He said he liked the guy, but he never felt hypnotized. John smoked until the end of his life.

Lennon in November 1980 He released his latest album “Double Fantasy”. In December of the same year, Lennon was shot and killed outside his apartment in New York City. He was 40 years old.

“John Lennon was very focused and very expressive,” Mintz said of their friendship. “But as we got to know each other better, I also noticed his vulnerabilities, his jealousies, his tendencies towards anger. I realized that he wasn’t all love and peace, peace and love. He embraced these concepts and stuck to them. (But) he didn’t always apply them, realizing his humanity.” “I was there.”

“Yoko had a reputation for being extremely stoic and humorless,” Mintz continued. “He always had the air of being the one to tear up the Beatles, but he didn’t do that. I also noticed his vulnerabilities. It made sense that the two of them would find each other.”
