NEW YORK — Blood, Sweat & Tears singer David Clayton-Thomas has died. He was 84.

The voice behind hits including “You Make Me So Very Happy” and “Spinning Wheel” is said to have died peacefully at St. Michael’s Hospital in Toronto on Wednesday. A spokesman didn’t give a cause of death.

One of his two Grammy Awards was for the band’s self-titled record, which topped the Beatles “Abbey Road,” Johnny’s Cash’s live album from San Quentin, the 5th Dimension’s “Age of Aquarius” and Crosby, Stills & Nash’s debut to win album of the year in 1970.

Clayton-Thomas was a petty hoodlum in Canada before he found his calling as a musician. Despite leading a nine-piece band complete with a horn section, Clayton-Thomas said in 2023 that he considered himself a blues player.

“Give me three chords and I’ve got a song,” he told bestclassicbands.com.

Clayton-Thomas was onstage with Blood, Sweat & Tears in 1969 when they were one of the bigger acts at Woodstock. The band performed nine songs including the aforementioned hits. They also providing music for the 1970 Barbra Streisand movie “The Owl and the Pussycat.”

Clayton-Thomas left the group in 1972. He recorded more than a dozen solo albums and toured on his own.

He was inducted into the Canadian Music Hall of Fame in 1996.

That organization’s website describes him as “a homeless street kid” who ran away from an abusive home as a teenager and learned to play guitar in jail when a fellow inmate left his instrument behind.

Clayton-Thomas headed to New York City in 1966, where he got noticed by Blood, Sweat & Tears drummer Bobby Colomby and joined the band.

He discovered he needed surgery to fix a defective heart valve in 2010 while performing in Toronto. That scare is credited with inspiring him to make positive lifestyle changes.

“Through the years, he lost none of the attributes that made him one of the greatest vocalists of his generation,” the Canadian Hall of Fame notes. “That unmistakable voice is soaring and sunny, but a dark, sombre shade of blue.”
