In an interview with Billboard, Graham Nash had some harsh words for bandmate David Crosby when asked about the future of Crosby, Stills and Nash.

“Right now, I don’t want anything to do with Crosby at all. It’s just that simple,” he said. “In my world there will never, ever be a Crosby, Stills, Nash & Young record and there will never be another Crosby, Stills & Nash record or show.” While declining to say what exactly Crosby has done, he did continue by saying, “I don’t like David Crosby right now. He’s been awful for me the last two years, just fucking awful. I’ve been there and saved his fucking ass for 45 years, and he treated me like shit. You can’t do that to me. You can do it for a day or so, until I think you’re going to come around. When it goes on longer, and I keep getting nasty emails from him, I’m done. Fuck you. David has ripped the heart out of Crosby, Stills, Nash & Young.”

Nash did note that he was “sad” about the current state of his relationship with Crosby, adding that he was hoping they’d be able to reconvene for a covers album they started working on with producer Rick Rubin. Nash’s latest, This Path Tonight, will be released on April 15 via Blue Castle.
