Even for a supergroup known for its legendary infighting, Graham Nash’s comments on David Crosby in a couple of recent interviews were pretty damn harsh. If Nash is serious and dead-set on his words, CSN will never make music together again.

Billboard first reported that Nash dropped some bombs on Crosby when he spoke to Dutch magazine Lust For Life:

These fighting words come after Crosby’s schism with Neil Young last year, a result of Crosby insulting Young’s relationship with actress Daryl Hannah, but it looks as if Crosby’s assholery was not limited in its scope. Billboard pressed Nash for further comment, and he told the magazine, “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.”

Well, he didn’t rule out a Crosby, Stills, Nash & Young show...also, he’s still following Crosby on Twitter. Cue Nash checking in on Crosby periodically over the coming years and feeling a little pang of painful nostalgia each time until, tearfully, he rips off that last Band-Aid.
