Tommy DeBarge, singer of the R&B group Switch, and member of the famous DeBarge family has passed away.

According to TMZ, a family member said Tommy suffered from liver and kidney failure over the years. He recently took a turn for the worse and was hospitalized until his death Thursday.

Tommy and his brother, Bobby, were founding members of Switch, which had a huge influence on future bands in the genre, including DeBarge … the group composed of their siblings.

Tommy rose to fame in Switch in the mid to late ’70s — the group recorded hits like “There’ll Never Be,” “I Call Your Name” and “Love Over & Over Again.”

Bobby and Tommy left Switch to mentor their younger brothers and sister in DeBarge, but Bobby died of AIDS-related complications in 1995.

Tommy was 64. Rest in peace.
