Back in 2014, Neil Young announced that he would never again tour with Crosby, Stills, & Nash, a decision seemingly stemming from some nasty comments David Crosby made about Young’s current girlfriend Daryl Hannah. And now, it looks like Crosby’s cantankerousness has also pissed off Graham Nash and broken up CSN for good. In a new interview with Dutch magazine Lust For Life, as Billboard reports, Nash essentially says that he’s done dealing with Crosby’s bullshit:

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 … How can I not be sad? Look at the music we probably lost. How can I not be sad about that? The truth is, after being totally immersed in me and David and Stephen and Neil’s music, I’m done. I’ve had 10 years of it. Leave me the fuck alone. I need to concentrate on me now.

Nash also spoke to Billboard, saying, “Right now, I don’t want anything to do with Crosby at all. It’s just that simple. 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.” He declined to offer any specifics about what Crosby had done, only stating, “I was letting Crosby be who he is. I let people play their hand in front of me, and I let him do it and then I make a decision.”

Nash is releasing the solo album This Path Tonight next month, and he plans to focus on touring in support of that. Crosby and Young are both also touring on their own, and Stephen Stills’ band the Rides are releasing a new LP entitled Pierced Arrow in May.
