Folk singer
Judy Collins heard Clayton-Thomas one night at a club uptown and told her friend, drummer
Bobby Colomby, about him. Bobby's band, Blood Sweat & Tears, had broken up four months after releasing its debut Columbia album,
Child Is Father to the Man. Colomby was impressed with Clayton-Thomas's vocal talent and he invited him to join the band. They took the reformed group into the
Cafe Au Go-Go in the Village. In his 1974 autobiography,
Clive: Inside the Record Business,
Clive Davis, then president of
Columbia Records, described his initial impression of Clayton-Thomas singing at the Café Au Go-Go: He was staggering... a powerfully built singer who exuded an enormous earthy confidence. He jumped right out at you. I went with a small group of people, and we were electrified. He seemed so genuine, so in command of the lyric... a perfect combination of fire and emotion to go with the band’s somewhat cerebral appeal. I knew he would be a strong, strong figure. Clayton-Thomas's first album with the band,
Blood, Sweat & Tears (which was released in December 1968) – despite being self-titled, it was actually the band's second album – sold ten million copies worldwide. The record topped the Billboard album chart for seven weeks and charted for 109 weeks. It won five
Grammy Awards, including Album of the Year and Best Performance by a Male Vocalist. It featured three hit singles, "
You've Made Me So Very Happy", "
Spinning Wheel", and "
And When I Die" (on the Hot 100, each peaked at No. 2 and lasted 13 weeks) as well as a rendition of
Billie Holiday's "
God Bless The Child". (Seeking to capitalize on the newfound fame of the singer, in 1969
Decca Records purchased the master tapes of the blues-oriented Roman Records material, dubbed in horns to make it sound more like Blood, Sweat & Tears, and released the album
David Clayton-Thomas!) The BS&T band went on a
United States Department of State–sponsored tour of Eastern Europe in June–July 1970. It is now known that the State Department pressured the group into the tour in exchange for a U.S. residency permit for Clayton-Thomas, The tour and its aftermath is the focus of a 2023 feature-length documentary titled
What the Hell Happened to Blood, Sweat & Tears? With Clayton-Thomas fronting the band, Blood, Sweat & Tears continued with a string of hit albums, including
Blood, Sweat & Tears 3 which featured
Carole King's "Hi-De-Ho" and Clayton-Thomas's "Lucretia MacEvil", and
Blood, Sweat & Tears 4, which yielded another Clayton-Thomas-penned hit single, "Go Down Gamblin'" and "Lisa Listen to Me". ''
Blood Sweat & Tears' Greatest Hits'' album has to date reportedly chalked up over seven million copies in worldwide sales. Blood, Sweat & Tears headlined at major venues around the world: the
Royal Albert Hall, the
Metropolitan Opera House, the
Hollywood Bowl,
Madison Square Garden, and
Caesars Palace, as well as the
Newport Jazz Festival and
Woodstock. It was the first rock band to break through the Iron Curtain with its historic
United States Department of State–sponsored tour of Eastern Europe in June–July 1970. A documentary about the tour was released in 2023 titled
What the Hell Happened to Blood, Sweat & Tears? including interviews with Clayton-Thomas. The documentary's premise was the Iron Curtain tour caused the band to lose much of its counterculture fanbase now that the band was seen to be working directly with the government. In the early years Clayton-Thomas lived on the road, travelling all over Europe, Australia, Asia, South America, the US, and Canada with Blood, Sweat & Tears. The constant touring began to take its toll. Clayton-Thomas left the band in 1972, exhausted by life on the road.
Variety later described Clayton-Thomas's decision to leave as ruining the band who "needed every bit of his sweat and swagger." By the mid-1970s, the founding members began to drift away to start families and pursue their own musical ambitions. ==Subsequent career==
