NEW YORK - Joni Sledge, who with her sisters recorded the enduring dance anthem "We Are Family," as part of the vocal group Sister Sledge, has died, according a family statement posted on the group's official Facebook page.
"On yesterday, numbness fell upon our family. We welcome your prayers as we weep the loss of our sister, mother, aunt, niece and cousin," read the statement.
Sledge was found dead in her home by a friend in Phoenix, Arizona, on Friday, the band's publicist, Biff Warren, said. A cause of death has not been determined. He said she had not been ill. She was 60.
Sledge and her sisters Debbie, Kim and Kathy formed the Sister Sledge in 1971, but had their breakout success in 1979 with "We Are Family." The dance song became an anthem of unity and women empowerment.
Sledge is survived by an adult son besides her sisters and other relatives.
