David Clayton-Thomas (born David Henry Thomsett, 13 September 1941) is a Grammy Award-winning Canadian musician, singer, and songwriter, best known as the lead vocalist of the American band Blood, Sweat & Tears. Clayton-Thomas has been inducted into the Canadian Music Hall of Fame and in 2007 his jazz/rock composition “Spinning Wheel” was enshrined in the Canadian Songwriter’s Hall of Fame. In 2010 Clayton-Thomas received his star on Canada’s Walk of Fame.

Clayton-Thomas began his music career in the early 1960s, working the clubs on Toronto’s Yonge Street, where he discovered his love of singing and playing the blues. Before moving to New York City in 1967, Clayton-Thomas fronted a couple of local bands, first The Shays and then The Bossmen, one of the earliest rock bands with significant jazz influences. But the real success came only a few difficult years later when he joined Blood, Sweat & Tears.

In 1964 Clayton-Thomas and The Shays recorded a rendition of John Lee Hooker’s “Boom Boom”. This led to a New York engagement for the Shays on NBC-TV’s Hullabaloo at the invitation of its host, fellow Canadian Paul Anka. Abandoning the bars on the strip, Clayton-Thomas began performing in Yorkville Village’s coffeehouses. He immersed himself in the local jazz & blues scene dominated by the likes of John Lee Hooker, Joe Williams, Sonny Terry and Brownie McGhee, Lenny Breau, Oscar Peterson, and Moe Koffman. Clayton-Thomas made his mark more forcibly with his next band, The Bossmen, one of the first rock bands anywhere to include jazz musicians. In 1966 he wrote and performed the R&B-driven anti-war song “Brainwashed”, which became a major Canadian hit, peaking at No. 11 on the national RPM chart.

Clayton-Thomas’s first album with the band, Blood, Sweat & Tears 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”.
In 1972 Thomas released his first Columbia solo album after BS&T, simply titled “David Clayton Thomas”. In 1973 the second solo album Tequila Sunrise was issued by Columbia. In 1974 he issued the Harmony Junction album on RCA. In 1975 Thomas returned to front Blood Sweat & Tears again on the Columbia albums New City and, in 1976, More Than Ever. In 1977 they released Brand New Day on the ABC label. In 1978 Thomas issued another solo album on ABC, titled simply Clayton. In 1980 BS&T issued the MCA album Nuclear Blues, which also included Thomas. Later in the decade Columbia issued the double live BS&T album Live And Improvised again with Thomas. In 2004, Clayton-Thomas left New York for Toronto and launched an All-Star 10-piece band. Since then, he has toured and recorded almost a dozen albums under his own name.

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.”

BS&T continued with a string of hit albums, including Blood, Sweat & Tears 3 which featured Clayton-Thomas’s “Lucretia MacEvil” and Carole King’s “Hi-De-Ho,” and BS&T 4, which yielded another Clayton-Thomas-penned hit single, “Go Down Gamblin’.” Blood Sweat & Tears’ Greatest Hits album has to date reportedly chalked up over seven million copies in worldwide sales.[citation needed]

BS&T headlined at major venues around the world: the Royal Albert Hall, the Metropolitan Opera House, the Hollywood Bowl, Madison Square Garden, and Caesar’s Palace, as well as the Newport Jazz Festival and Woodstock. It was the first contemporary band to break through the Iron Curtain with its historic United States Department of State-sponsored tour of Eastern Europe in May and June 1970). In the early years Clayton-Thomas lived on the road, travelling all over Europe, Australia, Asia, South America, the US, and Canada with BS&T. The constant touring began to take its toll. Clayton-Thomas left the band in 1972, exhausted by life on the road. By the mid ’70s, the founding members began to drift away to start families and pursue their own musical ambitions.
