About Bill Champlin
William Bradford Champlin is an American singer, keyboardist, guitarist and songwriter. He formed the band Sons of Champlin in 1965, which still performs today, and was a member of the rock band Chicago from 1981 to 2009. He performed lead vocals on three of Chicago's biggest hits of the 1980s, 1984's "Hard Habit to Break" and 1988's "Look Away" and "I Don't Wanna Live Without Your Love". During live shows, he sang the songs originally performed by founding guitarist Terry Kath, who had died in 1978. He has won multiple Grammy Awards for songwriting. The National Association of Recording Arts and Sciences (NARAS) awarded Champlin the Most Valuable Player peer award for male background vocalists in 1980. Both albums sold poorly due to lack of adequate promotion by his record company, although the latter album did include a pair of minor hits on the Billboard Hot 100 ("Sara" and "Tonight, Tonight").
