‘He wanted to give people hope’: David Clayton-Thomas, Canadian singer of Blood, Sweat & Tears, dies at 84

David Clayton-Thomas believed people could start over.

That belief, his daughter Ashleigh Clayton-Thomas said Thursday, shaped both his life and the way he saw others.

“He knows that there is hope and that nobody is born bad,” she said.

“Sometimes bad choices are made, but that doesn’t mean that you can’t turn your life around and make things better for yourself and your family. He felt he was an example of that, like, ‘Look at me: I came from nothing, I was in the jailhouse, and now I’m at Woodstock.’”

The Canadian singer, whose raspy, soulful voice helped make Blood, Sweat & Tears one of the biggest acts of the late 1960s, died Wednesday in Toronto at age 84, his publicist said.

He died peacefully at St. Michael’s Hospital due to complications from ongoing cancer, Ashleigh Clayton-Thomas confirmed.

Long before he helped define jazz-rock, won Grammys, and sold over 40 million records, Clayton-Thomas had a deeply troubled upbringing.

Born David Henry Thomsett in Surrey, England, he was the son of Fred Thomsett, a Canadian soldier, and Freda, a British music student. His parents met in London while Freda was performing for troops.

Following the Second World War, the family relocated to Canada, settling in the Toronto suburb of Willowdale. A young Clayton-Thomas had a fractured relationship with his father, according to his publicist Eric Alper. By age 14, he left home and had to fend for himself on the streets, bouncing in and out of various jails and reformatories.

A turning point came in jail when he taught himself to play guitar, picking up an instrument left behind by a departing inmate. After being released in 1962, he changed his name to David Clayton-Thomas to break ties with his troubled past and establish a new identity in the Toronto music scene.

“Those mistakes never stopped haunting him,” said Ashleigh Clayton-Thomas.

“I think he wanted to make it his mission to be like, ‘You can come back. Just because you made bad choices, it doesn’t define who you are.’”

American-Canadian rockabilly singer Ronnie Hawkins recognized Clayton-Thomas’s talent early on and mentored him. Before long, he was fronting his own bands, including David Clayton-Thomas and the Fabulous Shays, and Bossmen.

Clayton-Thomas’s career shifted course one night in New York City, when folk singer Judy Collis heard him perform and was blown away by his voice, Alper said. That led to an introduction to drummer Bobby Colomby, whose American jazz-rock band Blood, Sweat & Tears needed a new singer.

After joining the band in the late ’60s, Clayton-Thomas became a key part of the band’s international breakthrough. Their self-titled second album — his first with the group — spent seven weeks atop the U.S. Billboard chart in 1969 and won the Grammy Award for album of the year in 1970.

It famously edged out the Beatles’ “Abbey Road” in that year’s Grammy race, powered by hits including “You’ve Made Me So Very Happy” and “And When I Die,” as well as Clayton-Thomas’s own composition “Spinning Wheel.”

Clayton-Thomas told the Canadian Press in 2006 that “Spinning Wheel” was partly inspired by Joni Mitchell.

”I had an enormous crush on Joni Mitchell,” he said, recalling seeing her sing at a Toronto club in the ’60s.

”She was 18 years old and absolutely stunning and sang like an angel and wrote pure genius. Her little line about ‘the painted ponies’ . . . in (her song) ‘Circle Game’ stuck in my mind. And so when I wrote ‘Spinning Wheel,’ somehow or another ‘painted ponies’ crept into it, and that was courtesy of Joni Mitchell.”

His daughter said his greatest joy remained performance itself.

“He loved being on stage and he came alive when he was able to bring people into that world,” she said. “That was really the thing that made him the most happy — bringing them joy, bringing them peace through music.”

As a child, she said, she saw that world up close while travelling with him on tour.

“I definitely remember going out on the road being like a 10, 12-year-old little girl just running around backstage,” she said. “I was the daughter of everybody there. Everybody was my big uncle.”

She recalled a childhood spent in dressing rooms, hotels and airports while her father toured.

“He really just loved performing,” she said. “He loved singing for people.”

By the ’70s, Clayton-Thomas had embarked on a solo career, though he would rejoin Blood, Sweat & Tears for various stints over the decades.

He earned a 1996 induction into the Canadian Music Hall of Fame and a 2010 star on Canada’s Walk of Fame, while “Spinning Wheel” entered the Canadian Songwriters Hall of Fame in 2007.

Ashleigh added Clayton-Thomas also found meaning in later years through mentorship and connection to younger musicians particularly after returning to Toronto.

“He was really happy to be back in Canada. He was grateful to be able to connect with people from his early days, and his favourite thing would be to go down to his local jazz bistro and hang out with a bunch of musicians,” she said.

“He really enjoyed that stewardship of being able to take someone under his wing and guide them even just a little bit. Maybe they can avoid some of the pitfalls that he went through.”

Ashleigh says he was also involved with Peacebuilders Canada, a non-profit supporting youth facing barriers as they navigate the justice and education systems.

“He wanted to give people hope that they can do anything that they put their mind to. He was a very wilful person and he really believed that you can do anything if you wanted it bad enough.”

A memorial concert honouring his life and music will be held at a later date, said publicist Eric Alper, with proceeds benefiting Peacebuilders Canada.

Ashleigh said she’s grateful she got to have one last chat with her dad on Father’s Day.

“We had a great conversation and he complained about Trump,” she laughed. “And he talked about the World Cup.

“He was always very outspoken, sometimes to his detriment, but he never shied away from it.”

Clayton-Thomas is also survived by his daughter Christine Graham.

“He was a giant,” Ashleigh Clayton-Thomas said. “The world is a little dimmer today. He was a big light.”
