Singer William Guest, a member of Gladys Knight & the Pips, has died. He was 74.
Guest's sister-in-law, Dhyana Ziegler, says he died on Thursday in Detroit of congestive heart failure.
Guest performed with the Grammy-winning group from 1953 to 1989. They released such hits as I Heard It Through The Grapevine and Midnight Train To Georgia.
Gladys Knight & the Pips were inducted into the Rock and Roll Hall of Fame in 1986 and the Apollo Hall of Fame in 2006.
After the group ended, Guest and another member, the late Edward Patten, formed a production company.
Guest later served as chief executive of Crew Records. He released his autobiography Midnight Train From Georgia: A Pips Journey in 2013 with Ms Ziegler.
"I am so glad we finished the book, so his wonderful life and legacy will be celebrated throughout eternity," she said.
"My heart is broken, but I know his legacy will live on," said Guest's daughter, Monique Guest.
