OCEANSIDE, Calif. — Bill Isles, an original member of the chart-topping R&B group The O’Jays, has died at his Southern California Home. He was 78.

Isles died of cancer last month at his home in Oceanside, just north of San Diego, according to his son, Duane Isles. The funeral for Bill Isles was held Saturday.

Bill Isles was featured on songs including “Lonely Drifter” and “Lipstick Traces” before he quit the group in 1965. Duane Isles says his father was The O’Jays’ tour manager between 1971 and 1974, when the group released its biggest hits, “Love Train” and “Back Stabbers.”

The O’Jays were inducted into the Rock and Roll Hall of Fame in 2005.

Isles is survived by his wife, Laural, seven children, seven grandchildren and three great-grandchildren.
