Mark Volman Dead: The Turtles Co

Mark Volman, the co-founder of ’60s rock band The Turtles and one-half of ’70s duo Flo & Eddie, has died. He was 78.

Volman died Friday following a “brief, unexpected illness,” a representative for the musician told The Hollywood Reporter.

“Always funny, always upbeat, and a spirited and inventive performer, we will miss him greatly,” Volman’s attorney Evan Cohen wrote on Facebook Friday.

Born in Los Angeles in 1947, Volman first broke through with the Turtles in the mid-’60s, founding the group with Howard Kaylan, Al Nichol, Jim Tucker, Chuck Portz and Don Murray. Volman served as a vocalist in the band, which had its first hit in 1965 with a cover of Bob Dylan’s “It Ain’t Me Babe,” which spent 11 weeks on Billboard’s Hot 100. They had other hits, including “She’d Rather Be With Me,”
