Louis Armstrong

David Clayton-Thomas, the lead singer of Blood, Sweat & Tears whose husky, high-strung tenor on “Spinning Wheel,” “And When I Die” and other hits helped make the so-called brass rock band among the most popular acts of the late 1960s, has died at age 84. He was a stocky, onetime street fighter and petty thief in Canada who briefly became a rock superstar, the front man of a nine-member group that sold millions of records and won two Grammys for its self-titled second album. Backed by horns, keyboards and percussion, his urgent shout was a signature voice of the era. A spokesman says Clayton-Thomas died Wednesday in Toronto.
