SHE was the original rock chick, hanging out with the likes of The Beatles, Eric Clapton and The Rolling Stones, marrying Mick Fleetwood twice, experimenting with drugs and relishing the flower power hippy culture.

As a Sixties model along with her sister Pattie, who was married to George Harrison before running off with Eric Clapton, Jenny Boyd was swept along in the new music, fashion and free love culture of the time... making her way from the fashionable haunts of London’s Carnaby Street and Chelsea, to the flower power movement in San Francisco and the meditation centres of India.

“It was very exciting. It was an amazing time and a very different time. There was something about the Sixties that was magnetic. The world was opening up to me,” she reveals.

Today, Boyd, now 72, is reflecting on the extraordinary journey in which her looks secured her a job as a photographic model with fashion designers Foale and Tuffin while she was still at school.

By 16, she was appearing in glossy magazines, flying to New York shoots and appearing on catwalks at home and abroad, falling in with the musical movers and shakers of the time and dating Mick Fleetwood, who lived nearby.

“We’d go to clubs with Pattie and George and the rest of The Beatles and I always loved rock and roll. But in the end, I realised there was more to life.

“I went to San Francisco to help a friend open a shop. I knew nothing about flower power, but suddenly I found myself as part of the counter culture. And music was a very important part of that.”

Over the years, she had an on-off relationship with Fleetwood. They married at 21, divorced, married again and divorced, had two daughters together, Lucy and Amelia, and remain friends to this day.

“We always stayed in touch. He’d take me out for a drive. It was so easy and comfy being with him. There was something very familiar about him. He was quiet, very funny, but we were both horrifically shy. We just had a connection.”

Now she has written her memoir, Jennifer Juniper (the hit song Donovan named after her), charting her life with the musicians, photographers and other creative talents of the day, when she snorted cocaine, drank a lot of booze and endured a lot of loneliness.

When she had children the dynamics changed, she adds.

“I didn’t like being on the road because it was very much about the show and you’re always in hotel rooms. I wouldn’t drink in those days because either I was pregnant or looking after the little ones. I was the only one with children and had to make sure they stayed quiet.”

While they were together, Fleetwood’s star was on the rise while he descended into hard drugs and booze, became more and more absorbed with his band, and embarked on an affair with band cohort Stevie Nicks.

“The drugs thing really got started when we moved to Los Angeles in 1974. There was always drinking on the road,” Boyd recalls. “It was the beginning of everybody in the entertainment world starting to take cocaine.

“When they met with Stevie and Lindsey (Buckingham), at the place where they recorded in 1975, it was almost dripping off the walls. Coke was everywhere.”

Today, Boyd has a much calmer life. She’s been married to David, an architect, for 23 years, whom she met on a trek to Nepal.

Fleetwood lives in Maui, Hawaii, and they keep in touch. She talks about him as if she still loves him. Does she?

“Oh yes, but I’m married. But as person, I do. He’s very dear to me. He’s like a brother because we’ve known each other since we were young,” she says. “We have something that’s very special.”
