Neil Young recently announced from the stage that CSNY would never tour again, which prompted lots of questions. David Crosby then chimed in that Young is very angry with him for unspecified reasons. And when Young danced around the subject in his recent Howard Stern interview, he wouldn’t even say Crosby’s name. And apparently it all has to do with… Daryl Hannah?

As Rolling Stone points out, the conflict seems to stem from Crosby’s comments to The Idaho Statesman back in September. When discussing Young’s recent divorce from longtime wife Pegi, Crosby said he’d never separate from his own wife of 37 years and suggested that Young’s current girlfriend is “a purely poisonous predator.” Reports since September have suggested Hannah, the actress known for ’80s hits such as Blade Runner, Splash, and Steel Magnolias, is Young’s new girlfriend. Here’s what Crosby told The Statesman about it:

I just don’t feel the urge to go try something new. And I happen to know that he’s hanging out with somebody that’s a purely poisonous predator now. And that’s karma. He’s gonna get hurt. But I understand why it happened. I’m just sad about it. I’m always sad when I see love get tossed in the gutter.

Crosby later tweeted that he had no regrets about his comments. Now Crosby and Young’s (former?) CSNY bandmate Graham Nash has offered some further details on this conflict. On SiriusXM’s Ron And Fez show, Nash confirmed that Young is dating Hannah and said he understands why Young is pissed at Crosby: “You’ve got to understand: Neil Young knows what we bring to this music. He’s not a fool. He’s just a little upset right now. And I understand it.” He also said he’s still holding out hope for a CSNY reunion: “It would be sad to me if the music of Crosby, Stills, Nash & Young didn’t go forward because of an inappropriate statement by David to Neil about his relationship with Daryl Hannah. If we’re not more grown up and if we’re not more realistic about what the true value of our friendship is, it would be very sad to me.”

In the meantime, Crosby Stills & Nash are planning to tour the UK without Young next year, and Young’s new Storytone is out this week.
